1968 Buick Special Deluxe (basically, a 4-door Skylark). I was 16 in 1976, and “inherited” it from my Mom. It had a 350 cid V8 engine with a 2 barrel carb. Revving the engine at a stoplight would rock you side to side enough to make you seasick. It would haul. I saved my money from mowing yards, and paid $500 to get it painted BLACK. What a great car...
Almost forgot - gas ranged from 55 to 75 cents per gallon, and then started to run up over a dollar.
