GM J-bodies are usually pretty horrid and the Chevy Cavalier (post 2000) is definitely one of the worst.

At this point I'd have to say 80s GM G-body and the Impala/Caprice "Donk , box, and bubble" is possibly the worst custom trend I've seen. In the south, they're all over, and worse are the "Branded" donks with the Kool-aid man, etc. Although, the Skittles one is often good to follow if you're looking for a drug…

The most foolish automotive purchase I ever made was about eight years ago, via Ebay, while drunk.
