BillM , I had a 1969 Plymouth GTX, but not a convertible. Fun car w/440 6 pack, pistol grip 4 on the floor. I like your tastes in cars!
Other ones I had was 1961 Chevy bubble top, just a 283. 1964 Chevy Impala SS, 327, 4 speed, factory tach and console. 1965 Mustang w/ 289. 1967 Oldsmobile Cutlass, 330 Ci engine, three on the tree and a tire smoking fun car. Then up to 1975 Ford Hi-boy. Came w/360 and auto trans. I swapped in a 4 speed and warmed up and rebuilt 390 from a Galaxie 500. Also had a 1966 Chevelle w/396. Now I drive a 2018 Subaru Forester. LOL. Great winter vehicle for Iowa.
I realize new cars are faster then the old ones, of my day. However I remember riding in a 1969 Dodge Dart with a friend in college. He had some special edition with a 440 and auto trans. Pedal to the metal at 60 MPH and it would get sideways! The good old days! A Toyota Camry would probably beat it now. Thought the fast cars were gone in the 1970's. I was wrong!
