FHP is using a TON of different cars, most of them unmarked. They have a few 05+ Mustangs and a few 04 Cobras....all unmarked. You would NEVER know from looking at them.
The best one i ever seen the FHP driving was a done up Maurader i thought it was just some guy until someone passed us doing like 90 and he threw the lights on.. Talk about the best time i chose not to speed..
