The DVSA MOT history is free, permanent and far more honest than a freshly valeted forecourt car. Here is how to read mileage gaps, advisory wording and model-specific fail patterns on used Vauxhalls before you make an offer.
A rear door that refuses to open is one of the Meriva’s more annoying party tricks, but it is often a cheap cable or latch fault rather than a terminal bodywork problem.
