Whats the most you spent on junk?

Couple years ago I bought a 2005 Magnum R/T, had about 95k miles on it, well equipped, paid $3500.00 CAD for it, did a complete brake rebuild, and front end, struts, major tune up, serpentine belt, oil pressure sensor, oil temp sensor. Drove it for a couple months, heading to work one morning, driving slow in traffic, suddenly it started jerking, and making grinding noises. Transmission crapped out, shop quoted me $5 to 6k for a rebuild.:wtf:
Put a used one in for $1900.00 and sold the car for $5000.00 CAD, had invested about $7200.00 by then.

Several years ago, an acquaintance was looking for a clean Chevy Suburban. I found one, super clean, low mileage, rust free truck, put about $7700.00 into it only to have him bail on me. Said his wife wanted a minivan. I sold it for $4500.00 after being stuck with it for about 8 months.:mad:
