Character mistake: In an early episode, Villa mentions Rosewood's "banana colored" '69 GTO to his then girlfriend. Rosewood's GTO is a "banana colored" '68 GTO.
Character mistake: Rosie and Villa may be at the pinnacle of their respective careers, but neither knows squat about cars. Villa identifies the burned out hulk of a Pontiac as a '71 Lemans, when it is obviously a '70. Then Rosie has the gall to disparage a '69 GTO as a lemon, when everybody and his brother prefers the 69 over its predecessor, to the tune of more than $10K.
