My wife's W169 A180 Cdi was booked in today , local garage , for it's MOT and a minor service. Had the car ex demo back in March 2012 and has now covered nearly 90,000 miles. Up until today it's only needed a vacuum valve (£40) and two headlamp bulbs (£18) and a front wheel bearing (£30) plus the normal pads,discs,wipers,tyres and a new battery about 6 months ago. I had a call to say it had failed the MOT this morning - wing mirror indicator unit not working and two rear tyres worn on the outside edge. Picked the car up this afternoon and the bill was £280.00 for the MOT, minor service, indicator unit and two 16" Toyo tyres . Wife was well pleased but had to have a dig at my "C" class which cost over £400 for a "B" service alone a few weeks ago.
