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.
