You sure steve? Our car has been probed a few times at MOT...
Open the bonnet and get someone to rev, check if there is any un necessary movment in the engine. If not look down by the manifold and see if everything there is light and still in one piece (don't touch, fookin warm!)
Get the car started and get someone to pump the accelerator quite lightly and listen under the car, if its a blow out you will hear it.
