While binging on CSI Miami (*puts on sunglasses: YEAAAAAAAAAAAAAAAHHHHHHHHHHHHHHHHHHHH*) on Netflix I got to Season 6, Episode 17: "To Kill A Predator" in which they claim that there is a car-rental company in Miami that specializes in "green-cars" and therefore was able to rent a bio-diesel Dodge Charger.
The opening sequence has the car running down a guy, and the engine noise is very obviously not diesel.
I know CSI: Miami has another episode where they try to talk about street-racing/F&F type stuff and have a FWD Eclipse "drifting" around a parking lot.
There is also a Numb3rs episode with terrible car knowledge.
Anyone have anything else?
