its not a matter of the cops just pulling you over and then finding out your driving a turbo car whilst on your Ps
If the registered owner of a car is on their Ps, (you for example) and the car is turbod. It comes up on their computer straight away.
from what ive been told their computers now scan every number plate automatically and lets them know if there is discrepencies
its like getting pulled over if your driving a car with no rego, they already know your cars out of registration
so your on the hit list now, they will target you and really F#ck you if they catch you again with defects,.. i assure you of this
So wise choice on not driving it and getting all your defects fixed
