Found a guy selling a Nissan 300ZX Twin Turbo in near mint bone stock condition for $1000.00 (yes, that is one thousand dollars) because it dumped all its coolant on the ground and made loud clattering noises, he thought the engine was bad. After I bought it, I put a water pump on it.......and drove the crap out of it for a couple years......and sold it for 10 grand.....yea, it needed a water pump (did it myself with the timing belt in a few hours and 300 bucks in parts)..... I'd love to find one of those every day.
