Viewing a used car is exciting, but it's also your best chance to uncover its history before you part with your money. Whether you're buying from an independent dealership or a private seller, asking the right questions can save you from expensive surprises. Here are the key things to enquire about, along with what to look for in the answers.

Service History: The Car's Medical Records

A full service history is more than a stack of paper—it's proof that the car has been maintained properly. Ask to see the service book, stamped and signed, plus any invoices for work carried out. For an independent dealership that also offers automotive servicing, they may have carried out the work themselves, so ask for their records.

• Can I see the full service history? Check that services were done at the correct intervals, usually every 10,000 to 12,000 miles or annually, whichever comes first.
• Were any services missed or overdue? Gaps can indicate neglect, which may lead to problems with the engine, brakes, or suspension later on.
• Who carried out the servicing? A mix of main dealer and independent garage stamps is fine, as long as the work was done to manufacturer specifications.

If the seller can't provide paperwork, treat it as a warning sign. You might still buy the car, but factor in the cost of a full service and potential repairs.

Accident Damage and Insurance Write-Offs

Nobody wants to discover their new car was badly repaired after a crash. Ask directly about accident history, and don't be fobbed off with vague answers. Check for mismatched paint, uneven panel gaps, and overspray on rubber seals or trim.

• Has the car ever been in an accident? Even minor bumps can hide structural damage if repaired poorly.
• Is it an insurance write-off? Categories like Cat S (structural) and Cat N (non-structural) mean the car was deemed uneconomical to repair by an insurer. Cat S cars should be professionally repaired and re-registered, but they're harder to insure and resell.
• Can I see repair invoices? A reputable seller will have these to hand. If not, walk away.

An independent dealer should be able to show you a clear history check. If you're buying privately, arrange your own check before parting with cash.

Cambelt, Chain and Major Mechanical Work

The cambelt is a critical component—if it snaps, it can destroy the engine. Ask when it was last changed, and get the invoice as proof. Intervals vary, but many cars need a new belt every 60,000 to 100,000 miles or every five to ten years.

• When was the cambelt last changed? If it's due soon, budget for the work, which can cost several hundred pounds.
• Was the water pump and tensioner replaced at the same time? It's good practice to do these together, so ask for evidence.
• If it has a timing chain, any rattle on start-up? A rattling chain can mean expensive repairs are on the horizon.

Also ask about the clutch, brakes, and tyres. A car with worn tyres or grinding brakes will need money spent immediately.

Mileage: Average Annual and What It Means

Mileage alone doesn't tell the whole story. A car with 100,000 motorway miles may be in better condition than one with 40,000 miles of short town journeys. Ask for the average annual mileage, and check it against MOT records for consistency.

• What's the average annual mileage? The UK average is around 10,000 to 12,000 miles per year. Much lower could mean lots of cold starts, which wear engines.
• Is the mileage warranted? Get this in writing. Clocking is rare but possible, especially on older cars.
• Does it match the MOT records? Mileage is recorded at each MOT, so you can spot discrepancies.

High mileage isn't a deal-breaker if the car has been well maintained. In fact, a high-mileage car with a full service history can be a bargain.

Ownership, Finance and the Seller's Motivation

Understanding why the car is being sold can reveal a lot. A private seller might be upgrading, but they could also be offloading a problem. Ask about ownership history and any outstanding finance, which is a legal minefield.

• Why are you selling? Listen for evasive answers or a story that doesn't quite add up.
• How long have you owned it? A short ownership period might mean the car has hidden faults.
• Is there any outstanding finance? If so, the car isn't legally yours until the finance is cleared. Ask for a finance settlement letter or a clear history check.
• How many previous owners? Fewer owners is generally better, but it's not a guarantee of quality.

Always ask to see the V5C log book and check the seller's name and address match. If they won't show it, walk away.

Before You Hand Over Your Money

Once you've asked these questions, take a test drive on different roads, including a stretch of motorway if possible. Listen for unusual noises, check all electrics, and look for warning lights on the dashboard. If you're not confident, pay for an independent inspection—it's money well spent.

A good independent dealership will welcome your questions and provide honest answers. If you feel rushed or pressured, that's your cue to leave. Buying a used car should be a positive experience, and the right questions will help you find a reliable motor that suits your needs and budget.
