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

1978 I saw 2 different adds in local paper for 70 Hemi Cudas. one was $2,800 the other was $2,500. I couldn't afford either and ended up buying a 69 Roadrunner for $550. Drove roadrunner my senior year and blew engine on my 18th birthday. Two weeks later was in the Army and 43 years later I still remember the adds for the Cudas.
