Ive been reading round and apparently for the smoke test the engine is revved from idle to redline a maximum of 6 times
It says this test 'should not do any damage to a well maintained engine'.
Now as far as I know its been maintained as it should be, I dont much like the prospect of some numpty in a garage ragging the shit out of my motor, considering I never go above 3.5/4k...... I assume if you refuse to allow this to happen your car cannot pass the MOT?
What happens when you allow them to have fun with your loud pedal, that the engine DOES break? What sort of comeback do you have???
