Just passed my MOT with no advisories - which is good - but they did pick up that the frame number is different from the one on record at DVLA - seems that the number has been misread at every previous MOT - the one zero does look like a six - but is is a zero - definitely has not had a new frame so 0 out of ten for observation for the last ten mots!
Daft thing is that the mechanic who picked it up also did the last 4 MOTs!
