This one was mine, a 1998 Mercedes W208. The nice things about it were the cool Mono-Wiper, the engine (supercharged 2,3L M111) and the seats that were perfect for my height. It had a terrible ASR system but came with a LSD, so it was lots of fun in the winter.
The not-so-nice things about it were that the ignition randomly would not recognize the key, a missing catalytic converter, two fist sized rust holes in the front control arms, rust all over the underbody and the absolute worst 6-speed manual transmission I have ever used.
It also had multiple alignments but it didn't take long for the steering-wheel to be off-center again. You could see the tail end "crabbing" in the rear view mirror. There was something very wrong with it, which can probably be attributed to one of the 7 previous owners.
This isn't even counting all minor annoyances like the frameless windows not lowering themselves when you open the doors (that was only a thing after the 1999 model year), the wind noise, the awful interior materials, the broken seat latch in the rear, the trunk lock not working... I could go on for an hour like this.
So anyways, what is the worst car YOU have ever owned?
My first car, a 1997 VW Jetta, the engine exploded and caught fire on my way to work one day. Can't say any car I've had since has been as bad.
I actually kinda like the looks of this generation of Jetta, but catching on fire and exploding has to be up there for worst car experiences lol
It wasn't until after that, I found out the 1997 model is one of the worst Jettas ever made. I shoulda got the manual 98 the dealer had instead. The fact they had so many 97s shoulda been a red flag.
