1977 Pontiac Astre. It was similar to the Chevy Vega. Bought it in 1986 shortly after getting grounded from using my parents' cars. (Something about crashing them too much.)
Piece of junk, and I paid waaay too much for it. Traded it in in 1988 as a down Payment on a Trans Am. I still have said Trans Am. My friends call it "the car that wouldn't die." They even had a pool going for "where will Ken break down" when I moved it back to Calgary from Grand Prairie. Nobody won, because nobody picked "no breakdown."
