What cars did you pass on buying in the 60s/70s because they cost too much

All three happened in 1985. First was a 70 Lime green 4spd aar cuda. Car was missing the 6bbl and had a single 4bbl on it. Guy wanted 3g for it. He was living in an apartment. Went back a week later with the cash and he had moved. No idea what happened to the car
second was a 66 triple black 396 4spd Chevelle convertible. Guy wanted 5g for it. Just couldn't pull together the cash for it
third was a 1969 302 Camaro. Neighbor had it and also wanted 5g for it. Sold it to his nephew before I could scrape up the cash
