When your car is complied you will have to get a blue slip so you can rego the car, the guys that do the blue slip will advise you whether or not you need to go to the RTA for a 3rd tier inspection......
I called the RTA about this '3rd tier inspection' & the chick sounded like she had absolutely no idea what she was on about. As far as I could tell, it is just to check that the VIN & Engine numbers match on the car & you're not trying to pull a shifty.....
Does anyone else have any more info on them?
