What do you need to look out for when shopping for your next car?

As the thing that gets you to work and allows you to do the school run, your car is one of the most important things you own – and replacing it is no simple task. To help you save some money, you may be considering purchasing a second-hand vehicle, but before you take the keys, perhaps there are some questions you should be asking first?

“Absolutely,” says Carl Hitchings from Heart of the South West Trading Standards. “Unfortunately, not all used-car sellers can be trusted. The number of rogue traders is on the rise with the result being that people are buying cars that aren’t safe to drive and are losing thousands of pounds,” he explains.

So, what can you do to protect yourself?

1. Know your rights as a consumer

When buying a used car, you have legal rights that the trader must meet:

  • The car must be accurately described when advertised
  • It should be safe to drive unless the seller says otherwise
  • You must not be pressured into making a purchase
  • The car should be fit for purpose.

“It’s good to understand your rights before buying a car so you know what issues to look out for,” Carl says. “You should also research the seller’s history and reviews to see if they are reputable.”

2. Watch out for rogue traders masquerading as private sellers

“Be very wary of cars being sold on the roadside. The seller may be a trader masquerading as a consumer in an attempt to deny your full consumer rights," Carl explains.

When buying a car privately, you have fewer consumer rights, which is why it’s twice as important to research the seller – don’t automatically assume what they tell you is true.

3. Ask to see proof of the car’s documentation

Good cars come with full documentation to help prove that they are worth buying. Asking for evidence of these documents before buying a second-hand vehicle could save you money, time and stress.

“We receive complaints regularly from individuals that bought a second-hand car online, but when delivered, came with no documents. Many of them had paid in advance,” Carl says. “When they tried contacting the seller again, they couldn’t reach them.”

If buying your car online or over the phone, ask for photo evidence of the vehicle identification plate and the documents (they should match), including the VC5 registered keeper logbook (which helps to prove ownership), to ensure you receive everything you need to make the right choice.

4. Check the vehicle’s service history

Ask the seller to send you a photo of a recent hire purchase check to show they can legally sell the car to you, as well as the current MOT certificate and any invoices for recent or major work on the vehicle.

"You should also check if the seller can guarantee that the car will be safe to drive and everything works correctly. Ask if they will put this on the contract. If not, consider walking away," Carl says. "If the seller agrees to any repairs or improvements, make sure these are recorded on the sales contract so that you know they will be done.”

Try searching the vehicle’s MOT history online to check the mileage and advisories – the advisories could be your next bill!

“If you have any safety concerns, don’t drive the vehicle, instead report it to Citizens Advice,” Carl says. “Refrain from taking the car for repairs, as this may cover up evidence to support your claim.”

5. Stay clear of used-car adverts that say ‘part-exchange to clear’

“It’s best to avoid any car adverts that use the terms ‘trade sale’ or ‘part-exchange to clear’ as these could be an attempt by the seller to constrict your consumer rights,” Carl advises.

When purchasing your car, it's useful to keep a copy of the original advert to prove any criminal misrepresentation. You could receive a reduction in price or claim a full refund if the seller has lied.

6. Contact Citizens Advice for help with rogue traders
