My car is booked in for an MOT today. When I took it in first thing this morning, I was told that it was scheduled for 11:00. I haven't heard anything yet. My next door neighbour suggested the garage, he also told me to stop worrying and that it would sail through. Can you all cross your fingers and toes, p!ease!
I am sure it will be fine - garages are not very good at ringing and saying its done. I have had that experience. They've probably done it hours ago and no-one has thought to contact you. I'd give them till 3 and call to check it's ready - as a rule if they find anything wrong they ring - so maybe no news is good news
I usually book it in for a service and MOT together. Saves two visits to garage. A lot of the time one service a year is enough, unless you do highish mileage. Oil and filters get changed, brake discs and pads checked and changed etc. On a major service they look at things like the cambelt inside the engine which on some cars needs changing every 75000 miles. The service book should tell you the intervals, and a good garage will know also.
