The mandatory vehicle inspection that I had to put M2 through was pretty thorough, and I got to watch the mechs put him through his paces. All the tests are in the open and there are signboards explaining what each station checks for.
The tests include an identity check to make sure the car you say is yours is yours, and no illegal mods. There is the brake test, and what appears to be an anal probe checking that exhaust levels are within tolerable limits. They check for engine noise at max rpm to ensure a happy car and happy neighbours.
Result: flunked the wheel alignment test and the headlight focus test. While I might have thought M2 was the picture of perfect health, guess I didn't realise he was actually myopic and limping around.
Had to make an appointment to have Mazda take fix up M2 before going for a retest. I do so hate the "F" grade.
