I don't think it's right to say that "cops" hate imports. Sure, some hate imports, some probably dislike them a little, and some probably love them. Also, there are probably cops that hate domestics. I've been pulled over only in a fixed up civic, several times, but each time I did something to atleast get noticed in the first place.
I've had friends that got pulled over for no reason in imports, but they were let go without tickets because they weren't assholes to the cop. A lot of people automatically assume they got pulled over just because of the car they're in...and act like a dick. That'll get you a ticket everytime. Also some of friends that were pulled over, the cops actually talked to them about their car and mods done.
