I like the transformers chase between the cop-stang and Bumble Bee. Mostly because of the symbolism of the classic muscle car wars.
As for my fav car chase fantasy...I'd have to go with ripping past Tag in a high speed pursuit on the freeway and after stopping, gettin a beer and talkin about how freakin cool that was. <sorry Tag had to pick you since I don't know any other cops
