Bad cars rarely fool people. People fool themselves.
It happens mid-viewing. The tyres look tired, but you can replace those. There’s no service book, but the seller’s friendly. And the warning light has been on for months, apparently, without any drama. Before long, buying a used car turns into an exercise in finding reasons to say yes.
Each excuse on its own? Possibly fair. All together, they can turn a good prospect into something you should seriously reconsider.
The fix is simple: decide your standards before you see the car. Be clear on what you need, what you can afford and which questions need answering. The viewing is there to test the car against those standards, not to rewrite them.
The Advert: Read It Like a Detective
Read it once for the features you like. Then read it again, slowly.
“Full service history.” “Excellent condition.” “Recently serviced.” Every one of those is worth following up. Ask what records exist, what the latest service included and whether there are faults the photos don’t show.
Before travelling, get the registration number and current mileage. Save the advert, plus any messages about the car’s condition.
Spare keys deserve a question too. A missing second key mightn’t be a deal-breaker, but replacing it could be an expense you hadn’t counted on.
Check the History Before You Book the Trip
Why do it at home? Time. You can read the results properly instead of squinting at your phone while the seller waits beside you.
Use Reg Check to look into the vehicle’s history before you arrange a viewing. Check what the report covers, including whether it looks at outstanding finance, recorded insurance write-offs and stolen vehicle markers.
Don’t stop at the most recent MOT pass. Read through the records.
Imagine the same suspension component has picked up an advisory at several tests. That doesn’t tell you exactly what’s needed now. But it gives you a sharp question: has it been repaired, and is there an invoice to prove it?
Mileage gets the same scrutiny. If a reading drops between tests, it needs explaining. Could be an input error. Don’t jump to conclusions, and don’t ignore it either.
A clear report is helpful. Still, it won’t tell you whether the clutch is worn or the air conditioning works.
Work Out the Real Cost of Buying a Used Car
Before you negotiate on price, figure out what you might spend afterwards.
Get an insurance quote for that specific car. Check its servicing requirements and ask when the next service is due. Look into major scheduled work, particularly timing belt replacement where that applies.
Then think about tyres, brakes and anything else nearing replacement.
So a car’s advertised for £500 less than a similar one. Is it cheaper? Not necessarily, once those bills are added in. Recent work is only reassuring if there’s evidence it was done.
And keep a bit of budget in reserve. Even a carefully chosen used car can need attention.
Set Up a Viewing That Works for You
Daylight if you can manage it. Dry weather too; wet panels make it harder to judge scratches and paint differences.
Before the chat starts, walk around the car. Look along the bodywork, check the panel gaps and inspect the tyres. Spot something? Ask about it.
Previous paintwork isn’t an automatic reason to walk away. The point is understanding what happened, and whether the explanation fits the car’s condition.
Then go inside and test things rather than assuming. Windows, mirrors, heating, air conditioning, locks: try each one. Check the boot and lift the mats to look for damp.
A few minutes’ effort. The faults those checks reveal can take considerably longer to put right.
The Cold Start
Ask the seller, if possible, not to warm the engine up before you get there.
Listen while it starts and settles. Keep an eye on the dashboard for warning lights that stay on. Something sounds off? Ask, and get a mechanic’s view if you’re unsure.
You don’t need to pretend to know more than you do. “I’d like that checked before I buy” is a perfectly reasonable reply to an unexplained noise.
Check fluid levels only when it’s safe and in line with the handbook. Never remove the coolant cap from a hot engine.
The Paperwork Deserves Your Full Attention
A quick look over the bonnet won’t cut it.
See the original V5C log book and make sure the vehicle details match. Compare the vehicle identification number with the car itself. And remember, the V5C identifies the registered keeper. It doesn’t prove ownership.
Then the service records. Invoices usually reveal more than stamps, because they show what work was carried out. Check dates, mileages and vehicle details.
If the seller mentions a major job, ask for the supporting record. No record? Then you have to decide how much uncertainty you’ll accept.
When the service book’s missing, an online service history check can search available records from dealerships and authorised dealer networks. Anything it finds helps you understand the car’s maintenance history and compare it with the seller’s invoices.
Bring in Help If You Need It
Nobody expects you to assess everything alone.
Consider an independent inspection if the car’s expensive, has recorded damage or leaves you uncertain about its mechanical condition. Ask what it covers, and read the findings before agreeing to buy.
The history records, paperwork and inspection are separate pieces of evidence. They should all describe the same car. If they seem to tell different stories, find out why.
Before You Pay
Agree exactly what you’re getting, including keys, documents and any accessories the advert mentioned.
Promised repairs go in writing. Check they’re finished before collection; don’t rely on an assurance they’ll be sorted later.
Get a receipt with the registration, purchase price, date, and buyer’s and seller’s details. Keep it with the advert and any correspondence.
Arrange insurance, make sure the keeper transfer is handled and tax the car as required before driving away. Vehicle tax doesn’t pass from the seller to you.
Not sure? Take a break before deciding. You don’t owe anyone a purchase just because they’ve given up time to show you the car. A long journey doesn’t make unresolved problems less important, either, and that’s the part of buying a used car people forget most often.
Leaving a viewing is easy. Wishing you’d left one is much harder.
