Surely you're doing something to get their attention
Had the Levin for 7 months and never got pulled once
and if the car IS legal, you can't get done for anything
It may also depend on what area you live, some are more strict. If the roads are dead, and when they spot a tinted loud car, they will follow you,few of them follow you for a few blocks (do a quick pnc) then pull off, most of them pull you over and give you a producure (2lazy to check).
There are some cops are quite safe in my area, we have now given nick names who are a complete ass (Big Ears) and to stay away from.
This was quite recent, bumped into a undacova cop in octy VRS, gave im a blast, found out he was a copper lol. Copper puts the window down, saying "Nippy little ting" lol
I personaly think its all down to what mood the copper is in.
