Most people judge a second-hand car by how shiny it looks. Wrong place to start. The smartest part of buying a used car happens long before the viewing, with the advert, the MOT records and a few blunt questions to the seller. Together, those can tell you whether the car’s even worth the drive.
That’s no small thing when it’s two hours away and priced a little too attractively.
On the day itself, take your time. Fresh polish and a vacuumed interior are pleasant. They tell you nothing about an overdue timing belt, or why the mileage at last year’s MOT is higher than the one on the dash right now.
Here’s what to look at, in order.
Step 1: Quiz the Seller First
Ask for the registration number if the advert doesn’t show it. Get them to confirm the current mileage and service history, too.
Then work through the basics. How long have they had the car? Why are they selling? Any faults or warning lights? Accident repairs? What maintenance has been done recently? And are both keys available?
You’re building a record to compare against the car and its paperwork later. Be specific, though. “Recently serviced” might mean a documented garage service. It might also mean an oil change on the driveway. Ask what was actually done.
Oh, and screenshot the advert. Handy if the details shift.
Step 2: Check the History Without Leaving Home
There’s not much sense spending a Saturday travelling to a car whose records already raise questions you can’t resolve.
Run the registration through Full Car Checks to review MOT history, tax status, recorded mileage and vehicle details. For outstanding finance, recorded insurance write-offs or stolen markers, see what the paid reports include.
The latest MOT pass? That’s the headline. Read the rest of the story.
Tyre wear flagged across several consecutive tests should prompt one question: were the tyres replaced afterwards? If corrosion appears, find out where it is and what work’s been done. An advisory can be harmless. It can also be an expense you hadn’t budgeted for.
Mileage needs a careful look. Readings should rise sensibly in date order. A lower figure might just be a recording mistake, but you’ll want a credible explanation, plus evidence, before going ahead.
Step 3: Add Up the True Cost
Here’s the thing: the price on the advert is only where the spending starts.
Check insurance before you get attached. Then look at servicing, tyres and any major maintenance coming due. Two cars at the same price can produce very different bills over the next six months, which is easy to forget when buying a used car on looks alone.
Compare similar examples with the same engine and specification. Mileage matters; condition matters at least as much. A higher-mileage car with steady servicing might deserve more attention than a low-mileage one with almost no paperwork.
Suspiciously cheap? Ask why. Some sellers just want a fast sale. With others, the bargain disappears the minute the car’s booked into a garage.
Step 4: View It in Good Light
Turning up on a dark, wet evening makes the job far harder. Water masks marks. Bad light hides mismatched paint.
Before you get in, walk the car slowly. Sight down the panels for dents and uneven reflections. Check the gaps around the bonnet, doors and boot. Paint on rubber seals or trim is another clue.
Repairs don’t automatically rule a car out (plenty have had minor bodywork). What counts is whether the explanation matches what you can see.
Look hard at the tyres. Uneven wear, damaged sidewalls or tyres close to replacement all give you something concrete to raise.
Then try the kit inside. Windows, air conditioning, parking sensors, central locking: whatever’s fitted, make sure it works. You’d be amazed how often buyers spend the viewing talking engines and forget the everyday stuff.
Step 5: Hear It Start From Cold
Ask for the engine to be cold when you arrive, if possible.
As it starts and settles into idle, listen. Rattles that don’t fade, knocking, unusual smoke, warning lights that stay lit… note all of it.
Is a warm engine proof of a cover-up? No. The seller may simply have driven it that morning. But if you specifically asked for a cold start and it’s already running when you pull up, it’s fair to ask why.
Check accessible fluid levels when it’s safe, following the handbook. And never open the coolant reservoir while the engine’s hot.
You don’t have to diagnose every noise. If something worries you, that’s your cue to bring in a mechanic.
Step 6: Take a Proper Test Drive
Once round the block tells you the car moves. Not much else. You need to know how it behaves at higher speeds and once it’s warm.
Make sure you’re insured, then mix up the roads. Kill the radio for part of the drive.
Ask yourself a few questions. Does the steering feel steady? Do the gears change smoothly? Does it hesitate under acceleration? Knocks over bumps, or vibration when braking?
And does it suit you? Clear view at junctions, a comfortable driving position? A car can be mechanically sound and still be the wrong one.
When you get back, look again for warning lights or fresh leaks.
Step 7: Test the “Full Service History” Claim
Ask to see the records behind it.
Stamped book, invoices, digital records: whatever form it takes, check the dates, mileages and work completed. A folder of receipts is only useful if it relates to this car.
If the engine has a timing belt, find out the replacement interval and whether there’s evidence it’s been changed. Ask about other scheduled maintenance for that model as well.
No paperwork doesn’t prove nothing was done. It just means less evidence to lean on, and your decision should reflect that.
Step 8: Match the Paperwork to the Car
See the original V5C log book and compare its details with the vehicle itself. Check the vehicle identification number rather than trusting the number plate alone.
Worth knowing: the V5C shows the registered keeper. That’s not proof of ownership. Ask who owns the car and whether the seller is entitled to sell it.
The official GOV.UK advice on buying a used vehicle lists the document and identity checks to make.
Anything that doesn’t match gets explained before you pay. No exceptions. “We’ll sort it out later” doesn’t cut it.
Step 9: Tie Up Loose Ends Before Collection
Agree what’s included, and get promised work in writing. If the seller’s replacing a tyre or fixing a warning light, confirm it’s done before you collect.
Get a receipt with the vehicle registration, price, date, and both buyer and seller details. Keep it with the advert, your messages and any supporting documents.
Make sure the keeper transfer is dealt with. Sort your insurance and vehicle tax before you drive away, because the seller’s tax doesn’t transfer to you.
And finally? Leave yourself the option to walk. The long journey, the money spent on checks, the daydream of it on your drive all count for nothing if serious questions remain. Plenty of buyers learn that lesson the hard way when buying a used car.
Another one will turn up. Book another viewing rather than buy something you’re already unsure about.
