you have just been lucky emsta. i have been pulled over 3 times in the 7 yrs ive had my car and in all instances it was just day to day driving. coincidentaly it has only started happening in the last 3 yrs with a the "hoon" this and "hoon" that and the fact that my car doesnt look stocker anymore with rims exhaust and suspension.
i got defected for the first time a couple of weeks ago for uneven tyre wear and low exhaust pipe which was 1cm too low. fair enough the exhaust was low but getting a major defect and a fine because of my wheel alignment settings was abit of a joke. even when i was getting the car cleared by vic roads, one of the inspectors checking another car had a chuckle to the inspector say "this should be a good one, whats the list of goodies that you have to check?" he didnt have much of a reply when she said wheel alignment and ground clearance. it seems to be a given now days with imports, nothing like 7 yrs ago.
unfortunately the only way around this is to modify the car legally, an avenue that ash is taking i think, or make it appear legal. its a catch 22. you just have to make sure the big f-off turbo and all the other mods passes emmisions tests and get a piece of paper that says so. i'm assuming its a timely and costly process that most owners ignore, but it is achievable.
