THE COMPLETE USED CAR BUYING CHECKLIST

A used car is rarely a small purchase, yet many people spend more time researching a phone than the vehicle they'll rely on every day. The good news is that a methodical approach removes almost all the risk. Work through these stages in order and you'll buy with confidence.

Before you view: the desk research

The most valuable checks happen before you've even seen the car, from the comfort of your home. By the time you arrive to view a vehicle, you should already know its history.

• Run a free vehicle check on the registration to confirm make, model, colour, year and engine size match the advert exactly
• Review the full MOT history for advisories, failures and — crucially — consistent mileage
• Check the road tax status and cost so there are no budget surprises
• Consider a full history check for write-off, finance and stolen markers, which aren't in the free data
• Research the model for known common faults at the car's age and mileage

The paperwork checklist

When you view the car, the documents tell a story. Make sure you see:

• The V5C logbook — confirm the registered keeper's name and address match the seller, and that the VIN and engine number match the car
• Service history — a full, stamped service book or digital records show the car has been maintained
• MOT certificates — these should align with the online MOT history you already checked
• Receipts for major work — cambelt changes, clutch replacements and similar give peace of mind
• Two keys — a missing second key is common but worth factoring into the price, as replacements are expensive

The exterior inspection

View the car in daylight and ideally when it's dry — rain hides a multitude of sins. Walk around it slowly and check:

• Panel gaps — even and consistent all the way round; uneven gaps suggest accident repair
• Paint consistency — look down each panel in the light for colour mismatches or overspray
• Rust and corrosion — check sills, wheel arches, around the fuel cap and underneath
• Tyres — even wear across all four; uneven wear can mean alignment or suspension issues. Check the tread depth and the date stamps
• Glass and lights — chips, cracks and condensation inside lamp units

The interior inspection

• Wear vs mileage — a worn steering wheel, pedals and seat on a "low mileage" car is a classic clocking giveaway
• Electrics — test every window, the central locking, lights, heater, air con, stereo and dashboard warning lights
• Damp or musty smells — can indicate water ingress or previous flood damage
• Warning lights — make sure they illuminate then go out when the engine starts; a seller may have hidden a fault

Under the bonnet

• Oil — check the level and condition on the dipstick; a mayonnaise-like residue under the oil cap can signal head gasket trouble
• Coolant and brake fluid — at the correct levels and not contaminated
• Leaks — look for fresh oil or fluid on the engine and on the ground beneath
• Belts and hoses — no obvious cracks or perishing

The test drive

Never buy a car you haven't driven. Aim for at least 15 minutes covering different roads — town, faster A-roads, and if possible a short stretch of dual carriageway. During the drive:

• Start from cold if you can — many faults only show on a cold start, so be suspicious if the engine is already warm when you arrive
• Listen for unusual noises — knocks, whines, rattles, especially over bumps and on turns
• Check the brakes — they should pull up straight without vibration or pulling to one side
• Test the gears — smooth changes, no crunching or slipping; on an automatic, no harsh or delayed shifts
• Feel the steering — straight and true with no vibration or pulling
• Watch the exhaust — excessive blue smoke (burning oil) or white smoke (coolant) on acceleration is a warning sign

Sealing the deal

Once you're satisfied, the final stage is negotiation and payment. A few principles protect you:

• Use your research to negotiate. Advisories, upcoming tyre or cambelt costs and a missing second key are all legitimate reasons to ask for a lower price.
• Never pay in full before seeing the V5C. Pay by a traceable method, ideally bank transfer, and get a signed receipt.
• Make sure the tax is sorted. Remember road tax doesn't transfer — you must tax the car before driving it away.
• Get insured before you drive. Even a short drive home needs valid cover in your name.

None of this takes long, and most of it is free. The buyers who avoid expensive mistakes aren't lucky — they're prepared. Work through this list and you'll be one of them.
