A test drive is vital – it's the only way you can make sure that you will enjoy driving the car and that it is right for your needs. It's your main opportunity to make sure everything's in good working order – unless you've arranged for an engineer to look over the car for you.

Make sure you are insured to carry out the test drive. Check your own car insurance – you are looking for the words on the policy that says you can drive another car with the owner's permission. This is known as DOC or Driving Other Cars cover. Not all insurers include this so it really is important to check. Also, you should be aware that such cover is usually third party only. You can also check with the vendor to see whether they have extended their cover temporarily to 'any driver' so that they are covered while you test drive their car.

Make sure the engine is cold before you start by feeling the bonnet. If the car is already warm, the seller could be trying to hide a starting problem. Check for signs of excessive smoke when you start the car and when you're driving. The engine should be quiet and pull smoothly. Make sure there are no unusual rattles or clonks from the suspension.

The steering should be responsive. You should feel no vibration or 'free play'. The brakes should give you confidence and should stop the car in a straight line.

Check you can get the car into all gears smoothly without crunching. If the clutch doesn't start biting until the pedal has nearly reached the top, the clutch could be worn and may need to be changed.
