Since 1991:
1980 Pontiac Phoenix LJ - SUCKED. Worst car ever, only had it for 4 months.
1983 Chevrolet Celebrity V6 - Man, this was a great car. Like a true GM car, it ran bad longer than most cars will run at all. I lost it when it got towed and it would have cost more than the car was worth to get it back.
1987 Honda CRX DX - Fun little car, unfortunately it was an automatic. And it was before Honda could design an auto transmission that could shift without snapping your neck. Traded for next car on the list.
1991 Mercury Sable LS - Meh. It was loaded, though. My sister totaled it (not her fault).
1987 Chevrolet Sprint - Laugh all you want, I miss this thing. I love bare-bones, honest cars. Its only option was an AM/FM radio. It got more MPG (50) than it had horsepower (48). Clutch went out, and it was traded in.
1981 VW Rabbit LS - Great little car, but only had it 2 months. Brakes failed, so I sold it to a coworker that wanted a project.
1987 Acura Integra LS - This was it, the only lemon Honda ever built. It sucked. I gave it away, heard it died in a demolition derby.
1988 Chevrolet Sprint - This one had A/C and cruise control even. Cruise worked only on flat surfaces, and the A/C couldn't keep up with temps over 80. Unfortunately, it's the only car that ever broke down and left me stranded. Sold to a friend.
1993 Geo Prizm LSi - Great little car, sold it when I bought the next car.
2001 Oldsmobile Alero GL - Better than most people thought. I bought it in December 2001, first time I'd ever had a car the same year as the year I bought it. Sold to my sister who drove it for an additional 125k after the 90k I put on it.
1991 VW Passat GL - It was a beater, but fun. Donated to a relative that needed a car.
2001 Hyundai Accent L - This was made while Hyundai was slowly learning how to build good cars. Weak transmission and clutch. Put 120k on it in a year and a half, then sold it to my stepdad (who is now on his second Hyundai).
1998 Buick LeSabre - Would have been a great car, but it was cursed. Electrical problems, stalling out, trampled by elk, and so on. Traded it for next car.
2005 Dodge Caravan SE - 4 cylinder, so had no power. It was ok, but suffered from the typical Chrysler transmission problems. Traded it for my current vehicle.
2009 Ford Ranger XL - First brand new vehicle I've ever bought (thanks, $4500 rebate!), and I think I have to consider it the best vehicle I've ever owned. Manual everything, rubber floor, 2WD; but it has the upgraded stereo, 40/20/40 split seats, A/C and aux jack for my iPod. What else could you need? And now that I've smoked about a billion cigars in it, it smells great!
