What to check on a used car test drive
The test drive is where a used car either earns your money or loses it. It is also where buyers most often get carried away. The car looks good, the seller is friendly, and twenty minutes later you are shaking hands on something you barely listened to. A plan stops that.
Before you drive: insurance
This comes first for a reason. Citizens Advice says you need to make sure you are insured to test drive a car. If you have your own policy, check with your insurer whether you can drive someone else's car. If not, the trader's or private seller's insurance might cover you, but you need to ask. Citizens Advice is clear: don't test drive a car if you're not insured, as you'll be liable for any damage you cause and could get points on your licence. GOV.UK confirms that you must have motor insurance to drive on UK roads (Vehicle insurance).
Also check the car itself is legal to be on the road. GOV.UK's free vehicle tax check shows DVLA's record of its tax and MOT status.
View it in the right conditions
Citizens Advice recommends viewing in daylight and, ideally, in the dry, because damage is harder to spot when a car is wet. Ask the seller not to warm the car up before you arrive. A cold start is one of the most revealing minutes of the whole viewing.
The cold start
With the engine cold, turn the key or press the start button and watch the dashboard. Warning lights should come on briefly as a self-check, then go out. A light that stays on, or one that never comes on at all, needs explaining. Listen for rattles or knocking in the first few seconds, and look behind the car for heavy smoke.
How long, and where
Citizens Advice suggests driving for at least 15 minutes on different types of road. In practice, that means some slow town driving, a few junctions and roundabouts, and if possible a faster road where you can safely reach higher speeds. Turn the radio off. Ask the seller to keep conversation to a minimum while you concentrate.
What to check while driving
Steering
On a straight, level road, the car should not pull noticeably to the Driver's Side or the Passenger Side. Listen for knocks or clunks when turning at low speed, for example in a car park.
Brakes
When safe, brake firmly. The car should stop in a straight line without pulling, juddering or squealing. The pedal should feel firm, not spongy.
Clutch and gearbox
On a manual, the gears should engage cleanly. On an automatic, changes should be smooth with no flare in revs or harsh jolts. Note anything that feels hesitant.
Engine
Pick up should be smooth. Listen for whining, rattles or knocking, and watch the temperature gauge, if there is one, once the engine warms.
Suspension
Drive over a few bumps. Knocks, bangs or a car that keeps bouncing are all worth noting.
Everything electrical
Once you have stopped, test what you can: lights, wipers, windows, mirrors, heating and air conditioning. Small faults add up.
After the drive
Park up, leave the engine running for a minute and look again for warning lights, smoke and leaks underneath. Then switch off and take a moment before you talk money. Compare what you found with the MOT advisories you read beforehand. Our guide to checking a used car's MOT history shows how.
Hybrids and electric cars
Many checks are the same, but there are extras, including charging, the cable and range. See our guide to buying a used EV or hybrid.
Take notes as you go
It is easy to forget a small noise once the seller starts talking price. Pull over or wait until you have parked, then write down everything you noticed, however minor: a vibration at a certain speed, a stiff gear, a warning message that flashed up and went out. Those notes are your evidence when you negotiate, and your reminder if you decide to come back for a second look or an independent inspection.
If you are still unsure
Citizens Advice says that if you are still not sure at this stage, it is probably a good idea to look for another car. Alternatively, you can get an independent report, which it says will cost around £120 to £250, carried out by motoring organisations and specialist companies. It suggests calling The Motor Ombudsman for advice on where to get one locally.
The trade view
Sellers expect you to drive the car. They do not always expect you to drive it properly. Take your time, follow a plan, and do not let anyone hurry you. Before the drive, use our list of questions to ask a private seller. For the complete inspection and test drive checklist, see Buy It Right on the BangerWise home page.
