ok, let,s see...
76 Opel by Isuzu (was my mom's but it blew up and I wanted it, so she gave it to me) rebuilt the engine in my bedroom, got it running, my friend convinced me to have the head ported, so I took it off, lost interest, and decided to try sticking a chevy 2.8 v6 in. Never did get to drive the car, owned it for over 10 years and finally decided I was doing nothing with it, so I scrapped it. Still kicking myself to this day.
77 Toyota Corolla station wagon - had some weird overheating problem, never did figure it out, traded the car in. Almost bought another one recently...
At some point in here somewhere I bought an old (75?) Monte Carlo for $50 out of a guy's backyard. My friend and I tried to tow it home, but realized it had no brakes, so we left it on the curb in front of the house. I came back a week later with a tow truck, and the car was gone. Still had to pay the tow truck $40. My $90 mistake.
83 Dodge Omni - bought for $50, needed front end work and a clutch cable, never did it, just traded the car in.
81(?) Renault LeCar (yes, the ragtop) - never got it running right, can't remember right now what became of the car.
84 Honda Prelude - bought for $1500, the Corolla and the Omni were the down payment for this one, ran smooth even though it had probably over 250,000 miles on it (odometer died at 224,xxx), burned/leaked a quart of oil a week, fun to do reverse donuts in the snow. Actually decent off-road

oh, yeah, the tranny blew the same week I paid it off. I didn't want to change it, so I sold the car to a friend (who roped me into helping him change the tranny)
94 Hyundai Excel - damn good car. Beat the sh!t out of it and it got 30-33 mpg in town. Had it for 5 years, lots of memories. I'd have another one. Donated it when I couldn't get it to pass emmissions anymore. I think the computer was just going out.
96 Isuzu Rodeo - bought it because we were planning a family, but it was too hard on gas, so I traded it in for a...
2001 Pontiac Grand Am - nice to have something newer like that, had it for abut 5 years, but I couldn't afford to keep up the payments, so I sold it.
69 Volkswagen Beetle - rusted!!! I think I was just excited to buy my first bug, and I didn't know what to look for. Drove it for 2 years, then pulled the engine and scrapped the car.
72 Volkswagen Super Beetle - current daily driver for the last ~4 months. So far, it's ok, but I'm realizing that I don't like the way they're put together, and I want to trade it for an Opel by Isuzu so I can get it right this time.
I know I'm forgetting something, I thought I had more than that...
