Your first car.

My first car was a 1955 buick special riviera bought for $25 in 1984.

But just as I don't claim that John Denver was my first concert in 1976, but instead claim either Brownsville Station in '78 (at Carl Caspers) or Judas Priest/Iron Maiden in '83...

My first Mopar was a 1966 Coronet 440, poly 318 with PW and AC in 1985 for $500.
