Cars from the 60's-70's suck big time.
Sooo true. My first car was a 1976 Buick Century with 231 cc V6 engine, normally aspirated. The engine wasn't half-bad -- this was before emissions controls other than a PCV, EGR and catalytic converters so it *was* simple to work on -- but in every other respect it was dreadful by modern standards. 105 horsepower to move 3800+ pounds equals 0-60 in 17 seconds and 15 miles to the gallon, baby.
My first car was a 1960 Dodge Dart 2dr (Phoenix) with the 318ci V8 engine. It had 240 or 260 HP (opinions vary) and got over 20 MPG on the freeway... in spite of being 19.5' long, 6.5' wide, and about 4700 pounds wet. You can't compare the sixties and seventies at all.
