Buying a used BMW 5 Series: what to check before you hand over cash

The BMW 5 Series is a popular choice for those seeking a blend of performance and luxury. Before you buy, check the following to ensure you make a sound investment.

Paperwork

Start with the V5C document. Ensure it matches the seller’s details and that the Vehicle Identification Number (VIN) is correct. A full service history is essential. It indicates that the car has been well maintained. Look for stamps from reputable garages.

Bodywork

Inspect the bodywork for signs of rust, dents, or scratches. Pay attention to panel gaps. Uneven gaps may suggest previous accidents. Check for mismatched paint, which can also indicate repairs. Look underneath for any signs of corrosion.

Engine Cold-Start

When you start the engine, listen for any unusual noises. Knocking or excessive rattling can indicate serious issues. Allow the engine to reach its normal operating temperature. Check for smoke from the exhaust. Blue smoke often indicates oil burning, while black smoke suggests fuel issues.

Test Drive Checklist

During the test drive, assess the performance of the engine. It should deliver power smoothly without hesitation. Pay attention to the gearbox. Shifting should be smooth, with no grinding or delays. Test the brakes for responsiveness and listen for any unusual sounds.

Gearbox

Whether automatic or manual, the gearbox should operate smoothly. In an automatic, check for a delay when shifting. In a manual, ensure the clutch engages and disengages properly. Any grinding noises or difficulty changing gears may signal problems.

Electrics

Test all electrical components. Check the lights, windows, and infotainment system. Ensure that the air conditioning works effectively. Faulty electrics can be expensive to repair, so it is essential to verify their condition before purchasing.

MOT History

Review the MOT history for any past failures. This can provide insights into potential ongoing issues. Look for patterns in failures, such as recurring faults. An up-to-date MOT certificate is a good sign, but past records are equally important.
