We had them in the late 70’s and early 80’s. My dad bought them and bored out the blocks just to get a cheap basic transportation vehicle for family members. One friend put a 283 in one. They were never collector vehicles.
I sold my old cars a couple of years ago— 63 nova SS convertible and 64 nova 4 door (my grandmother’s car), both with 350s. I have my father’s 78 Ford pickup.
I guess the Cosworths are collectible perhaps.
