What’s the best deal you’ve gotten on cars or parts

I've been doing this for a long time, but probably the best one in recent memory was a deal I made with a former co-worker. He had 2 1983 Mustangs, both t-top cars, both had been original V6's, converted to V8, one had a 302/C4 in it complete, he thought the cam was wiped. The other one had a small block C6, no motor, both had 8.8 diffs swapped in, plus a set of freshly done SBF heads, crank, and rods. On a stand was a complete 351W with a Weiand 4 bbl intake and 650 Holley, block was cracked, plus a pile of other miscellaneous parts, and a 1995 GMC 3/4 ton 2wd extended cab truck, that ran and drove, with 2 sets of tires and wheels, needed front bearings and brakes, drove it home. All for $900.00 cash. I sold the truck the next day without touching it for $900.00. Oh and the "wiped cam" 302? he had tried to use a 351W firing order on it. I corrected that and that motor ran beautifully.
