I've had three MOT's in the last month on the two Alpina's and the Coupe and I'm pleased to say not one advisory amongst all of them.
I did once take the Alpina in for an MOT about 3 years ago and on talking to the Tester afterwards, he said that he could have given me an advisory on one thing but it was dubious and in his words "Anyone who cleans and polishes the inside of their alloys, deserves the benefit of the doubt" he said a clean car makes his job so much easier as he doesnt have to brush through the dirt to inspect things and get bits in his eyes when they drop down
I've always remembered that prior to taking a car in.
