Since no has has mentioned one, I'll post my first car.
1972 Dodge Challenger...Had a 318 Mopar ( IMSMC ), bucket seats, and rust everywhere. But, boy could that car MOVE!
And, it was one tough car...One night in early '86, I rolled it down a hill, into a river. Went back the next morning with a tow truck, pulled it out, let the water drain out ( just like in the movie Risky Business ), and drove it home. Jacked out a few dents, replaced a door, and drove it for a couple more years.
The kid I sold it to had it rear-ended while it was parked, and wedged it under a truck. It took two tow trucks to pull them apart, and in the end, the truck had $3,000+ damage to the back end, the the Challenger had a little scratch in the paint!
When I had it, it was nicknamed "The Green Weenie"...after the the last incident, it became known as "The Green Missle"...the car that cannot be destroyed!
Like others...boy I wish I had that car now!
