It's always good when a vehicle passes it's MOT without any problems, especially now they have new ways they can fail.
Then again, if a car is serviced regularly, there shouldn't be too much to go wrong. It also depends on where you get it MOT'd.
The place I've had my vehicles serviced for quite a few years, would rectify any small faults rather than fail it. Also helps if
a vehicle is serviced and MOT'd at the same time.
Too many people nowadays never get their car serviced, and rely on the MOT to find any faults, as well as getting the AA/RAC
to get them out of trouble.
