What's the WORST car/truck you've owned?

1971 Challenger. I was just out of high school. I thought the Challengers and 'Cudas were the best looking cars on the road. I found this 71 on a local Dodge dealer's lot. It was a very basic low optioned car, 318 auto column shifter, no console. I couldn't go any distance at all at highway speeds without it overheating. I put 48000 miles on this car , and the dealer never did fix it. After 24000 miles, it was out of warranty so I just drove it that way. The brakes were a real Adventure. When coming to a stop, you did not know if it would pull to the left, right, or sometimes straight. The fit and finish wasn't very good either. One day when I was washing it, I ran my hand under the cowl and found a triangular fold of sheet metal that put a gash on my left index finger. The most memorable thing about this car is I lost my virginity in the back seat. Ahhh the memories.
