What to check before the MOT

Start with missing - it accounts for 33.3% of failed tests on this model.
Then check not working and has excessive wear or free play, the next two most common reasons.
The most common advisory is has a serious fluid leak (7.8% of all tests) - not a failure, but money you will spend sooner or later.
Average recorded mileage at test is 10,201 miles, which is the number to compare any advert against.

11-15 years	69.09%	55
