Well, I read over everybody's posts and was trying to figure out what my best/worst vehicles would be, so I made it into a few categories:
Most fun/favorite: my 93 Mark VIII
Most dependable: 1991 Ford Ranger 2.3 5-speed 2wd .Trust me, that truck took tons of abuse during my teenage years raising hell on the road and farm, and the only thing that ever had to be replaced was brakes and the clutch.
Worst car: Would definitely have to be the 94 Honda Accord I had for a few months. Granted, it wasn't bad to me because I never put it on the road, but it was a total pain in the a$$ for alot of people. I bought it from my buddy who'd just spent $12k on it having a built JDM H22A (for those who know Honda-speak) and built LSD auto transmission swapped in it. He drove the car 20 days after getting it out of the shop, and the brand new transmission went out. By that point, he was out of cash to spend on it, so he sold it to me for cheap. I knew alot of money had been put into the car, so I figured I'd get around to fixing it someday, but then another friend came along and wanted to buy it for more than I had in it, so I sold it to him. He ended up first swapping another automatic into it, which burnt up after just a couple weeks, then swapping a 5-speed into it, which lasted maybe 3 weeks until the engine blew up on him one night when he was racing it. As for what happened to the car? It ended up being parted out lol.
As for a few other notes based on other posts:
87TTOPGT: I had a 95 T-Bird 4.6 for a couple months last summer. I bought it from a friend who was having financial troubles, and, even though I may not have had it long enough to form a solid opinion about it, my friend certainly had a strong opinion about it. He called me one day and told me he'd actually borrowed some money to buy his car back and if I would sell it back to him, which I did.
JAX: I love that 76 Ford. I had a 78 Bronco 4x4 (the BIG ones) with a 400, and it was a hell of a truck. It would go through anything you asked it to without a problem. I'd love to have another one and do a 460 swap, but with gas going higher and higher, that might not ever happen.
thaywood: I had a 81 Mustang coupe 2.3 4-speed, but mine didn't seem that sluggish. Granted, it was by no means fast or anything close to it, but it seemed peppy for what it was. I actually got it about 10 years ago when I was 16. I was wanting a foxbody Mustang for a 460-swap I never ended up getting around to and my friend's dad had it sitting out back at his shop and sold it to me for $50.
