Whats the best deal you have ever gotten?

Bought an older Ford Ranger that would not run for $100.00. The previous owner was moving and just wanted to be done with it. I found the motor had zero compression. Bought a timing belt for about $25.00 (internal serpentine rubber kind) and replaced the broken factory belt. Motor started up fine after that. And away I went!

Bought a 1985 Olds Cierra for about $1000.00 that the previous owner said had the automatic transmission failing. Took it for a test drive and it had a terrible vibration. Paid for it, drove it home, and found a broken motor mount. Replaced the motor mount, and no more vibration. Car drove just fine after that.
