Don't know that I really had a "worst car", I hated the Maverick, but it ran like a top.
I had a '75 F-250 with a '71 429 PI and a '73 frame (it had the dual piston calipers on the front) and when I finally quit blowing up tranies in it I couldn't keep the 429's lower end together, I kept over reving it. I couldn't keep a 460 in it either, I would over rev it and throw lifters. I guess that's why you shouldn't drag race in a 3/4 ton truck
Had a Ford Ranger, 2.3, cracked the head (common) and the wife cheaped out and wanted me to put on a used head. Same problem in three months. Replaced it again with a Ford reman head, a motorsports cam and Dnomax exhaust. That thing was WICKED in town. We drove it o Vegas and back, best MPG was 28, worst was 12, but not a lick of problems until the clutch went out, that took a weekend to get it bled out right.
Had an '85 Chevy shortbed, WOW!!
Bought it from a guy my dad knew, he'd gotten it in Cali. Dude owned a GM dealership and wanted this to pull his catermeran boat. The motor was too weak, so he dropped in a crate 350 (not sure what designation) crome headers and all topped off with Holley accesories. Tranny went out, he replaced it with a turbo 400. Then it wouldn't pass smog in Cali so it had to go! Light blue with silver, blue interior with the Flexsteel bucket seats and a cooler in the middle of them. 0-45 it was a turd, but hit 45 you better hold on because she was going somewhere FAST!!! Totaled it out on some unmarked road construction, I miss that truck!
'86 Suburban, motor got soft so I had a 400 built up for it, Comp cams 268H, Weiand Stealth, headers with 3 1/2" tubes and a crossover, topped with a Holley 610. Five 700R4 tranies later it sat while I tried to talk a builder into doing a turbo 400 for it. He talked me into a 350 conversion instead, I hated it but still got 13MPG if I kept it tuned up, not bad in a 4wd! Tranny went again, as well as it started eating starters so it sat and got a 4" lift and converted to 3/4 ton running gear. All was fine until the neighbors screamed to much and I got burnt by the city inspector, it had to go in 30 days
'79 Pontiac Gran Prix (I know I know!) it was dubbed the "Gehto cruiser" silver, I had the windows tinted in silver and found a set of "snow flake" wheels for it. Bought it for $300 with a bad motor. It had a 301, scarce as hens teeth and twice as expensive, and not really a good motor anyway! I found a 350 for $150 dropped it in and blew the tranny (seeing a pattern yet?
) found a turbo 400 for $25
and made it fit (if you have to ask you don't want to know!) and lowered it, I mean SLAMMED! Cut the front springs then clamped the rears with U-bolts. I put 37k on that car until the motor went and sold it for $500!
My '97 F-150 had the 4.2 V6 with a five speed, it didn't like being driven like a truck! Seriously! That truck pissed off more people than you can imagine, drive it like you think you should and the check engine light would come on after you pissed it off! I was the only one that could make it happy, none of my friends or wife could drive it, it thought it was a sports car and wanted to be driven that way, damndest thing I've ever seen! Hauled wood, hauled skidsteers and drove it like I stole it. Around 80k it blew the head gaskets. At 140k it lost the GEM (windows, dome light, widshield wipers etc ceased to work) the clutch and spun a rod bearing.
My favorite, my '67 Ford Fairlane 2dr hardtop in midnight metalic blue. God was that car a sight!! Had it for two months and it got beat with softball sized hail. I don't like to talk about it much.
My point, allmost all the problems I had with cars, were my problem
I guess I was fortunate in that aspect.
