Ever caught yourself defending a car you don’t even own yet?
Most of us have. The tyres are a bit worn (easy to replace). The service book’s missing (but the seller seems decent). There’s a warning light, which has apparently been on for months without causing trouble. When you’re buying a used car, those little explanations can pile up surprisingly fast.
Individually, each might hold water. Together, they can turn a promising purchase into one you should think twice about.
The best moment to set your standards is before the viewing. Work out what you need, what you can spend and which questions need answers. Then use the viewing to see whether the car lives up to all that.
Start With What the Seller Wrote
Read the advert once for the things you like. Read it again for the details.
Claims like “full service history”, “excellent condition” and “recently serviced” are worth chasing. What records are available? What did the latest service include? Any faults the photographs don’t show?
Get the registration number and current mileage before you set off. Save the advert and any messages discussing the car’s condition.
It’s also worth asking about spare keys. A missing second key may not stop you buying, but a replacement could be a cost you hadn’t considered.
Research First, Travel Second
Looking into a car’s background at home gives you time to take the results in. Doing it on your phone with the seller standing next to you is less comfortable, to put it mildly.
So before arranging anything, use Reg Check to look into the vehicle’s history. Review what the report covers, including whether it checks for outstanding finance, recorded insurance write-offs and stolen vehicle markers.
Then go beyond the latest MOT pass. Read the earlier records too.
Here’s an example. A car has had an advisory for the same suspension component at several tests. That won’t tell you exactly what needs doing today, but it gives you a solid question: has it been repaired, and is there an invoice?
Mileage needs the same care. A reading that drops between tests should be explained. It might be an input error, so don’t jump to conclusions. Just don’t ignore it.
A clear report helps. It still can’t tell you whether the clutch is worn or the air conditioning works.
Budget for the First Few Months
Before you negotiate on price, think about what you’ll spend afterwards. It’s one of the easiest things to overlook when buying a used car.
Get an insurance quote for the actual car. Check the servicing requirements and ask when the next service is due. Look into any major scheduled work, particularly timing belt replacement where applicable.
Then consider tyres, brakes and other parts that may be approaching replacement.
£500 less than a similar example sounds like a bargain. Is it, once those bills are included? Not necessarily. And recent work only adds reassurance if there’s evidence it was completed.
Hold a little money back as well. Even a carefully chosen used car can need attention.
Make the Viewing Count
See the car in daylight if you can. Dry weather helps, because wet panels make scratches and paint differences harder to judge.
Walk around it before getting caught up in conversation. Look along the bodywork, check the panel gaps and inspect the tyres. Notice anything that deserves a closer look, then ask about it.
Previous paintwork isn’t automatically a reason to reject a car. The goal is to understand what happened and whether the explanation matches the condition.
Inside, try the equipment rather than assuming it works. Open the windows, adjust the mirrors, test the heating and air conditioning, check the locks. Look in the boot and under the mats for signs of damp.
All of that takes a few minutes. Repairing what it uncovers can take far longer.
Request a Cold Start
Ask the seller, if possible, not to warm the engine before you arrive.
Listen as it starts and settles. Watch for warning lights that stay on. If you hear anything unusual, ask about it, and get a mechanic’s opinion if you’re unsure.
There’s no need to bluff. “I’d like that checked before I buy” is a perfectly reasonable response to an unexplained noise.
Check fluid levels only when it’s safe and in line with the vehicle handbook. Never remove the coolant cap from a hot engine.
Take the Paperwork Seriously
This deserves more than a quick look.
Ask for the original V5C log book and check the vehicle details match. Compare the vehicle identification number with the car itself. Bear in mind that the V5C identifies the registered keeper rather than proving ownership.
Then work through the service records. Invoices can tell you more than stamps alone, because they show the work carried out. Check the dates, mileages and vehicle details.
If the seller says a major job’s been done, look for the supporting record. Without it, you’ll need to decide how much uncertainty you’re prepared to accept.
And if the service book is missing? An online service history check can search available records from dealerships and authorised dealer networks. Any records it finds can help you understand the car’s maintenance history and compare it with invoices from the seller.
You Don’t Have to Do It Alone
An independent inspection is worth considering if the car’s expensive, has recorded damage or leaves you uncertain about its mechanical condition. Ask what the inspection covers, and read the findings before you agree to anything.
Treat the history records, the paperwork and the inspection as separate pieces of evidence. They should help you understand the same car. If they seem to tell different stories, find out why.
Before You Hand Over the Money
Agree exactly what you’re buying and what’s included: keys, documents and any accessories mentioned in the advert.
Put promised repairs in writing, and check they’ve been completed before collection. An assurance that they’ll be sorted later isn’t enough.
Get a receipt recording the registration, purchase price, date, and buyer’s and seller’s details. Keep it alongside the advert and relevant messages.
Arrange insurance, make sure the keeper transfer is handled and tax the car as required before you drive away. Vehicle tax doesn’t pass from the seller to you.
Still on the fence? Take a break before deciding. You don’t owe anyone a purchase because they spent time showing you the car, and a long journey doesn’t make unresolved problems matter less. That’s worth remembering every time you’re buying a used car.
Walking away from a viewing takes seconds. Regretting that you didn’t can last a lot longer.
