The rule of the thumb is to have a checklist that will guide you on what things to check for before you settle to buy. You should always be prepared to walk away when you are not convinced about an issue in the vehicle.

What to Look For When Buying a Used Car Checklist

When going to buy a used vehicle, it is important to carry a checklist with you. Here are what to look for when buying a used car from a dealership. This used car buying guide will make it easy for you to buy a good second-hand vehicle:

what to look for when buying a used car from a dealership

Engine

The engine works as the heart of a vehicle. Therefore, for you to enjoy a good driving experience, the engine needs to be in good condition. Therefore, before you settle down on a used car, the first thing to check is the engine. Here are the things to look out for in an engine:

Leaks

One thing that will tell you about the condition of the vehicle is a leak. Several fluids run around the engine, like oil and coolant. Fluid leaks are evidence that there is something wrong with the engine of the vehicle. A well-maintained vehicle should not have any leakages. 

You can only see leaks from under the vehicle. If you notice sludge build-up under the vehicle or oil on the ground, the vehicle has an oil leak. Also, open the bonnet and check for any leaks around the engine. 

You can take a photo or a video, which will help you scrutinize the vehicle underneath easily. Everything around the engine and transmission system and underneath the vehicle should be dry. 

Head Gasket

The other thing that will help you determine the condition of the engine is the head gasket. The head gasket is a vital component of the combustion chamber located between the upper and lower parts of the engine. A head gasket prevents engine fluids from getting in the cylinders. 

A blown head gasket is a sign that there is fluid leakage in the area. This makes the engine lose power and also produces some noise when driving. Buying a vehicle with a blown head gasket may cost you a fortune to repair. 

Open the engine top when the engine is cool. If you notice any light brown or white sludge, then that is a result of a blown head gasket. If you note any of these signs, do not buy the vehicle. 

Exhaust Smoke Colors

Colored exhaust fumes are a sign of trouble in the vehicle engine system. You can get to know the problem in the engine depending on the color of smoke coming from the engine. 

The black smoke color from the exhaust pipe could result from a clogged air filter. This prevents fuel from mixing with air properly, thus preventing the engine from working smoothly. This, therefore, demands the vehicle to burn additional gasoline, thus lowering feel efficiency and causing major engine problems. 

White smoke coming out of the exhaust pipe is a sign of leaks in the cooling system. When coolant is burnt up in the engine, it results in engine overheating, thus causing system problems. 

Blue exhaust smoke signifies that there is an oil leak in the engine. Oil leaks reduce the lubrication of engine components, thus increasing their wear and tear. If you note any of the above smoke colors in the tailpipe, then know there is a problem with the engine. 

Gearbox and Clutch

A faulty gearbox will cost you a fortune to repair. The gearbox transmits torque from the engine to the wheels. It also provides different transmission ratios enabling the vehicle to adapt the engine speed in various driving situations.

You can only know the condition of the clutch and gearbox from what you feel then what you see. Some signs you check out for are any shaking, chattering, and whirring sounds, and a burning smell coming from the gearbox. 

Take time to engage the gear of the vehicle and ensure it is smooth and quiet. The gears of a good second-hand vehicle should also be easy to change. A damaged clutch pedal feels spongy, hard to engage, chatters when accelerating, pulsates, and remains on the floor when engaged. 

Engine Sounds 

Another thing that will enable you to know the condition of your engine is the sounds the vehicle engine is making. As the engine runs, be very careful to listen to the type of noise coming from it. In case you hear knocking, clicking and tapping, grinding, or squealing is a warning that something is wrong in the engine system. 

Bodywork

One of the main things sellers use to sell second-hand is making them as presentable as possible. Therefore, you need to be very careful when doing a visual inspection from the cars outside, underneath, and inside. A good bodywork check on the vehicle will help you get an idea of the vehicle’s past. 

Check if there are any dings, dents, or signs that the vehicle may have gotten into an accident. Do not forget to check door seals and panel gaps for any probable leaks. The gaps between panels should be the same all around the vehicle.

Check the rear and front of the vehicle for any low-speed stunts. Open the boot and check the below the carpet. The panels under the boot carpet should be ripple-free and straight. 

If the panels are bent, it is an indication that the vehicle has had a front-end crash. In the event that the car documents say the vehicle has not had an accident and your bodywork checks show otherwise, do not buy the vehicle. 

Rust or Paint Issues

As you check the vehicle bodywork, look for any paint and rust issues. Look if the paint used on the vehicle is original. Having some shiny pain on an old car is an indication that the vehicle polished before the sale. 

Door jabs will help you know the vehicle’s original paint, and you can compare it with other body parts. Look out for is a paint overspray or some rough paint particles. This is a sign that bodywork or paintwork has been done on the vehicle. 

Rust is another course of concern on a second-hand vehicle. Check out the metal parts of the vehicle for any rust or blistered paint. Rust could have been triggered by stone chips and scratches that were left unattended. 

The other place to look out for rust is on the wheel arches, resulting from grit, road grime, salt, or water. 

Frame Issues

Another one of the used car buying tips and tricks is to check if it has any frame problems. At times car collisions and accidents do not always leave visible signs of damage. Walk around the vehicle and look for any creases, cracks, or rust on the frame. Check under the frame for any bent or missing component. 

Another thing to check when inspecting a second-hand car frame is the alignment. Park the vehicle on an evenly leveled ground and see if it is sitting evenly. Carefully check the rear and front bumpers for any dings and dents. Apply some pressure to ensure that they are well attached. 

Also, look at the undercarriage for any dangling or hanging parts. Poor alignment can cause doors to stick at odd angles. Make sure that the trunk and doors are closing and opening easily. It is advisable not to buy a vehicle with a damaged frame since it is risky to drive and may cost you a lot of money to repair. 

Mileage

Most second-hand vehicle sellers tend to reduce the vehicle of a vehicle to make them more sellable. You should not always trust the mileage that the seller gives to you. It is good to confirm if the vehicle mileage has not been tampered with. 

Low mileage means that the vehicle has not been used much, but it does not always mean it is good. To confirm the mileage, divide the number on the odometer with the car’s age. In most cases, vehicles with a high mileage tend to have a lot of wear and tear on their mechanical parts. 

However, some vehicles with low mileage could have worn out plastic and rubber parts under the hood due to neglect. If the vehicle was left unused for a long time, the undercarriage dries and becomes brittle, thus needing replacement. 

Another thing to consider when buying a used luxury car mileage is where it has been used. For instance, a vehicle with a mileage of 75 000 miles on mountains tends to have more damage than that with 75,000 miles on the highway. 

Therefore, you really have to consider the factors above when settling on the vehicle mileage. It is better to buy a used vehicle with moderately high mileage but well maintained than buying a low mileage vehicle that has been neglected. 

Wheels and Tires

Another thing to look for when buying a used hybrid car is its tires and wheels. A vehicle may be used but still have decent tires. Some tires and wheels may be worn out due to alignment and suspension system issues; thus, you need to be careful. 

The tires can also help you know if the mileage stated is correct or not. Vehicles with a mileage of 20,000 mileages in most cases still have their original tires. A low mileage vehicle with new tires is a red flag, and you should be quite cautious. 

Examine the wheels’ bulges, cracks, and scuffing and check the edge of each of the rims for cracks or dents. If the wheels and tires are worn out, you can negotiate to have the price reduced or replaced before purchasing the car. 

Interior 

You have to be very careful when examining its interior before you buy a used smart car. This will help you to know if the mileage is genuine or not. The interior of a vehicle with low mileage should be almost new. These are the things you check from the used car interior:

Boot

The boot of the vehicle you want to buy should have enough space to serve your purpose. Normally, it should be able to fit at least a spare wheel, mechanic kit, and other items you may want to carry around. 

Lift the boot carpet and see if it is dry. If you notice some wetness in the boot, then it may be a sign of some leaks. Look for the folding mechanism of the rear seat to see if it will give you additional space when required.

Mileage and Warning Lights

Once you get in the car, turn on the ignition and check for any warning lights. At this point, check for the figure on the odometer and divide it by the vehicle’s age to get its mileage.  

Electronics

Most modern vehicles have a lot of electronics in them. Therefore, it is crucial to check if the vehicle has the electronics you desire and if they are in good condition when buying a used car. 

While the vehicle engine is running, turn on the car heater and see how quickly and hot it will become. You should also switch the air conditioner to ensure it is functioning properly. Some of the warning signs you should look out for are uneven beams or fogged lenses. 

A dim beam is an indication that the bulbs need to be changed. You need to check the locking system, infotainment system, radio, climate control, and other electronic gadgets in the vehicle. 

Odor

When you get in the vehicle, do not only concentrate on what you can see but also the smell that comes from the car. A mildew, moldy or musty smell is a sign of water leaks. Confirm this by lifting the car carpet and checking for wet spots. 

Seats

You definitely want to buy a vehicle with good-looking and clean seats. The vehicle may be second-hand, but the seats should not be torn or ripped off. Vehicles with torn-out seats are most probably a high mileage. Ensure that the seat adjustments are working properly. Seat on the driver seat, and make sure that you can adjust it to your most comfortable driving condition. 

Pedals

The clutch, brake, and gas pedals will give you an idea of how long the vehicle has been in use. Check out for any wear and tear on the pedals. Worn-out pedals are a sign that the vehicle has been in use for a long time. 

Sound System

Check if the vehicle radio is functioning in both FM and AM receptions. If it has a CD player, load and ejects the disc to see if it works well. Also, test if your iPod or MP3 player connects with the sound system. 

Roof 

When still in the vehicle, have a careful look at the roof of the vehicle. Check the roof trim and headliner for any sags or stains. Stains are signs that the sunroom could be leaking. Also, ensure that the doors and windows are well-fitting. 

If the vehicle has a moon roof or sunroof, make sure that it opens and closes properly. After closing, check if it seals perfectly to avoid any leaks. Light a flashlight passes over the roof from the inside to examine if there are small tears.  

Exterior

The exterior includes the parts of the vehicle that you can see from the outside. So the exterior parts you should examine before you purchase a second-hand vehicle include:

Glasses

The glasses of a good second-hand vehicle should not have cracks or pocked areas. If the vehicle has cracks on the windshield, the best thing is to leave it since it will worsen with time. You can overlook small issues like a stone chimp but, of course, use it to negotiate your price down. 

Lights and Lenses

Make sure that the reflectors and light lenses of the vehicle are intact and are not missing, fogged with moisture, or cracked. Also, let someone confirm to you is the lights are working perfectly. 

Under the Hood

Before buying a second-hand vehicle, you should check its underhood. From that position, you will see if there are any hanging hoses or wires and signs of corrosion. Always do this inspection when the engine is cool. They include:

Hoses and Belts

When inspecting the underhood, squeeze the rubber hoses going to the air conditioner, radiator, and other components. The hoses should feel supple and firm. If they are mushy, cracked, or rock hard, then they have an issue. Also, feel if the belts are frayed or are in good condition. 

Fluids

Various parts of the vehicle work with the help of different fluids, mostly for lubrication. Check if the fluids are at the right levels. Also, check the oil colors to see if they need to be replaced. If the oil is amber in color, it shows that it was recently changed.

Watch out if the oil is foamy or grey or the dipstick has water droplets. This could be a sign of a blown head gasket or cracked engine block. Check the color and level of the transmission fluid. It should be pinkish and should not have a burnt odor. 

If the dipstick leaves some metal particles on the rag, it is an indication of a problem in the system. Inspect the automatic transmission fluid when the engine is running and hot. The brake and power steering fluid should be within the safe level. 

Battery 

You cannot forget to check the battery of a second-hand vehicle before the purchase. You, of course, don’t want to get stuck as you go through your business due to a dead or weak battery

Most of the maintenance-free car batteries these days feature an inbuilt charge indicator. A green indicator means that the battery is in good shape. A black or yellow indicator, on the other hand, means that the battery is weak or dead. 

The indicators, however, only reveal the condition and thus may not give accurate results on the health of the entire battery. If possible, unscrew the battery caps and check the level of the liquid electrolyte. 

A low liquid electrolyte level means that the car battery has been used for hard tasks. Also, ask a mechanic to do a load test and also check the battery’s charging system. 

Radiator

Examine the plastic reservoir that is joined to the radiator using a plastic hose. Check the color of the coolant. The coolant should be orange or greenish. A rusty or milky colored coolant needs to be changed. If you note a greenish stain on the radiator, it is an indicator of pinhole coolant leaks

Test Drive

It is very important to go for a test drive before you purchase a used vehicle. This will give you an experience of the vehicle. It may also help you discover some things you may not have noted from the visual inspection. 

A good vehicle should give you an intuitive and natural feel. You should also feel safe and secure when driving the vehicle. Feel how the vehicle accelerates and how it brakes. The test drive will also help you feel how good the steering is. 

As you go for a test drive, take the vehicle on sharp bends to see how balanced it is. Try the vehicle on different driving conditions and speeds. As you drive, listen if there are any irritating rattles or engine noises that are signs of engine problems. 

Documents

When you are done with the visual inspection and test drive, you have to check the vehicle’s documentation. The documentations should give show the entire history of the vehicle. 

The car documents should also come along with receipts of work carried out in the vehicle. Check the mileage on the document and see if it matches with what had calculated earlier. 

It should not also have a service book that shows when and where the vehicle has been serviced. Make sure that they have the vehicle logbook to ensure that they are the rightful owner of the vehicle. 

Car History

Before you buy a second-hand vehicle, you need to know its history. Get the correct details of the vehicle by asking the seller questions about the vehicle. In most cases, they will have braced themselves with answers; thus, you need to be very intelligent. 

Ask the seller when the vehicle was purchased first. If it has been involved in an accident before, how many times it has exchanged hands and also their reason for selling. 

You can also do some personal research about the vehicle just to ensure you are doing it right. See if the information that the seller gives matches what is on the documents. Check online free
