Ah, the good 'ol days...

Back in the mid 80s to mid 90s, I passed up:

77 Trans Am 400 4 speed T tops spun bearing $600
67 GTX Hemi auto no engine or trans $550
66 Charger Hemi auto stripped to the bare shell $250
70 Barracuda Gran Coupe 318 auto hit all the way back the driver side $150
67 Mustang coupe 289 auto engine locked up $150
73 Nova SS 350 4 speed rough but driving $250

and many, many more. These are the ones that jump to mind. Also did some rather regretful selling back then:

70 Cuda 340 4 speed red with black painted top, rough, no engine, sold for $600
70 Challenger SE 318 auto, engine seized, no windshield or hood, sold for $400
72 Charger SE 318 auto, inspected, running, driving, sold for $450
72 Charger SE 400 4bbl auto, rough but mostly complete, sold for $400
Again many, many more....
