Hey Dude,
With your above comment....is your car modified, and if so is it modified within the boundaries of the law??? If it isnt then you have to expect to be harrassed by the law on occasion.
I drive an modified import too and have been pulled over various times to be breath tested/car check and have had various fines but nothing i can really say i didnt deserve, dont take me the wrong way, cops get it wrong too but you dont take it up with the officer take it to the next level.
Also, some cops are jerks, just like the some civillians are jerks too.
Thats my thoughts.
