Don’t buy a used car until you check these things

Buying a used car can save you money – but only if you know what to look for. Here are the essential things to check before handing over your cash.

Buying a used car is like buying a house with fresh paint – it might look perfect on the surface, but the real story is hidden underneath. A shiny exterior doesn’t always mean the car is in great condition. Hidden accident damage, poor servicing, or mechanical problems can quickly turn a “bargain” into an expensive headache.

This handy guide gives you practical tips and tricks to inspect a used car like a pro, even if you’re not mechanically minded. From checking paperwork to taking a test drive, these easy steps can help you buy with confidence.

Remember, you can buy a used car right here on Carwow. We’re here to help you through every step of your car-changing journey.

Before you view the car

The first thing to do is do your homework on the car you’re eyeing up. Here are three things to look at:

1. Check the vehicle history

A history check can reveal whether the car:

• Has outstanding finance
• Was previously written off
• Has been reported stolen
• Has mileage discrepancies

Popular services include HPI checks and other online vehicle data providers.

2. Check the MOT history

Use the official UK government MOT checker to:

• Verify mileage records
• Spot recurring faults
• See past advisories and failures

The MOT history can reveal whether the car has been well maintained or repeatedly patched up.

3. Inspect the V5C log book

Make sure:

• The seller’s details match the V5C
• The Vehicle Identification Number (VIN) matches the car
• There are no signs of tampering

Avoid sellers who “don’t have the log book yet.”

Exterior and bodywork checks

When you see the car in person, here are a few things to do to check it’s in good condition:

1. Inspect the car in daylight

Always view the car:

• In dry weather
• During daylight
• When the car is clean

Rain and darkness can hide scratches, dents, and poor repairs.

2. Paintwork and panel gaps

Walk around the car slowly and look for:

• Different paint shades
• Ripples in body panels
• Uneven gaps between doors, bonnet, and boot

These can suggest previous accident repairs.

Top tip: Stand at one end of the car and look down the side for waves or distortions in the bodywork.

3. Tyres are important

Tyres can tell you a lot about how a car has been treated.

Check for:

• Uneven wear
• Cracks or bulges
• Matching tyre brands

Another thing you can do to check the tyre is inserting a 20p coin into the tyre thread:

• If the outer band of the coin is hidden, the tyre is likely legal
• If you can see the outer band clearly, the tyres may need replacing

Under the bonnet

Here are some simple mechanical checks near the engine anyone can do:

1. Ask for a cold start

Try to inspect the car before the engine has been warmed up, and listen out for:

• Knocking sounds
• Rattles
• Excessive smoke

A healthy engine should start smoothly.

2. Check the oil

Pull out the dipstick:

• Healthy oil is amber or light brown
• Thick “mayonnaise” sludge can indicate serious engine problems like a blown head gasket

Also check the car’s coolant levels, brake fluid levels, and signs of leaks under the car. Walk away if you see fresh puddles or wet patches under the engine.

Interior and electrical checks

You’ve checked everything on the outside of the car, and now it’s time to check inside. Here are three things to do:

1. Don’t ignore the cabin

Look for wear and tear in the cabin. Check:

• Steering wheel wear
• Driver’s seat condition
• Gear stick wear

Heavy wear on a “low mileage” car could suggest mileage tampering.

2. Check for dampness

Feel the following inside the cabin:

• Carpets
• Boot lining
• Floor mats

A damp smell or wet carpet could mean water leaks, flood damage, or failed seals.

3. Test every electrical feature

Turn on the ignition and check:

• Dashboard warning lights illuminate first
• Warning lights go off after the engine starts

Then test your windows, air conditioning, radio, wipers, and infotainment. Faulty electronics can be expensive to repair, so test everything.

The test drive

This is the most important check to do when considering a used car. Aim for at least a 15-minute drive covering town roads, faster roads, and uneven surfaces.

Here are three things to do while test driving:

1. Braking test

The car should:

• Brake smoothly
• Stay straight
• Avoid vibrations or screeching

Juddering can indicate warped brake discs.

2. Suspension check

Drive over:

• Speed bumps
• Rough roads
• Potholes (carefully)

Listen out for clunks, knocks, or bangs. These noises may suggest worn suspension parts.

3. Gearbox check

Test:

• Every gear
• Reverse gear
• Clutch biting point in a manual

The gearbox should feel smooth without crunching, slipping, or resistance.

Major red flags to walk away from

Avoid the car if you notice:

• Smoke from the exhaust
• Dashboard warning lights staying on
• Strong damp smells
• Uneven panel gaps
• Missing paperwork
• Suspiciously low prices
• Pressure-selling tactic

If something feels off, always trust your gut. It’ll save you so much hassle and money in the long run.

Extra tips and tricks for smart buyers

Here are some other things you can do to make your used car buying experience less stressful:

• Bring a friend, parent or partner: A second pair of eyes can spot issues you miss.
• Never rush: Take your time – a genuine seller won’t pressure you.
• View multiple cars: Comparing different cars helps you recognise what’s normal.
• Budget for repairs: Remember that even good used cars may need new tyres, servicing, brake pads, or minor cosmetic fixes.

Buying a used car doesn’t need to be stressful. By following the tips and tricks in this guide, you can dramatically reduce the risk of costly surprises after you’ve bought the car. The last thing you want is to spend thousands, only to fork out even more on repairs later.
