Coolest Car Movies

There was an awesome 70's made for tv cop movie with Angie Dickinson. I don't know if it was related to the Police Woman series or not. She was after a freeway killer called "The Fiddler" who listened to extreme bluegrass music while killing innocents with his souped up Dodge Tradesman Van. He drove with the engine cover off and they loved showing the totally decked out Smallblock. She got him in the end.

Did anyone mention DUEL?
And the TV show Hunter had scads of MOPARS
