Lately here in jax, we've had problems with people impersonating officers in unmarked vehicles. I would have no even pulled over until i was in a populated area/parking lot, and called your local PD to find out some info on the impending situation.
I also think your record, or lack there of for that matter, will help you in your situation since he didnt use laser or radar in his attempt to make his case.
im not a policia, just a lowly fire academy member, but ive experienced some situations like yours before.
hopefully things work out in your favor... keep us posted.
