I wouldn't say they hate all imports. I can definately say there is some bias towards domestics, but only perhaps due to the fact that (most) cops are older and there may be some bias at play, perhaps remembering muscle cars from their youth.
That being said, I think it has to do more with *asian* imports. My modded volvo, whilst sleeper looking, still has barely a muffler, some lowering and rims. It rarely if ever get pulled over. My DD, with wheels, tint, lound red paint job etc and expired tag has yet to get me cited.
I think part of it has to do with some biases and some profiling. They may not intentionally do it, but everyone has their own biases. When i see some ricer kid, chances are, I think they'll do something fuqtarded with their honda over the older muscle car owner.
It is what it is.
My car is factory....
Every single performance part and or modification it has was made in a factory somewhere.
