My first car I bought at age 16 -- was the largest ever production sports coupe : a
1974 Pontiac Gran Prix SJ455
The thing was a tank, but with a slapstick shifting, posi-traction rear end, and 390 factory HP, it had no problems getting me to where I wanted to go REALLY FAST!!!
For all you sharp-eyed film buffs ... yes it was the same make/model that Carrie Fisher drove in The Blues Brothers!
