Whats the most you spent on junk?

I've learned all vehicles are a money pit. Very few will yield equal too or more than you invest unless you have a TV show or run an auction for rich drunk millionaires.

My Dart. Never should have bought it. But I was young, into Mopar's and it had a 4 speed. I have probably close to $25k into it over 24 years. Some money spent several times due to mistakes and allowing other people to work on it.
Ill probably end up in the same boat eventually. Theres no way anyone makes money off these cars. I dont regret it though still get thumbs ups when i drive my car and its more fun than my toyota.
