Number 3 the eldest. She smokes in her car and it stinks. I've had to vac it, wipe down the dash and plastics and put a dangly air freshener in it. I was too embarrassed to take it for the mot in the state it was in. I reckon mot testers make a judgment about the way a car is looked after by the condition of the inside. It wouldn't have been fair to expect the tester to sit in it especially if he is a non smoker.
