I loved the American Motor Corp (AMC) cars: Pacer, Gremlin, Javelin. It's a real shame that AMC went out of business.
I really liked the Ford LTD sedans/station wagon products. Any detective TV series from the 1970's (Ex: Cannon, Barnaby Jones, etc) used Ford LTD/Lincoln Town cars. The Ford commercials had Ford's slogan of the 1970's: "Quiet, because it's a Ford".
I also like the 1972 Chevy Impala's styling and dashboard. Those were quite unreliable, but their styling made you forget about how much money you were paying on repairs.
The 1970's Cadillac's were really nice. Huge rich looking vehicles with the pimp mobile front grills.
Sadly those huge V-8 were so inefficient, that a 400 Cu In V-8 would only yield about 140 hp, which is on par with a modern 2.2 Liter 4 cylinder engine.
The one thing I remember about 1970's vehicles in general was lack of longevity.
It was quite rare for any of them to make it past 100k miles and have the odometer roll around.
Whereas today, many vehicles reach 200k miles and some even 300k+ miles.
Another thing I realized is the the 1970's Japanese cars used a technology that stuck around. Smaller overhead cam engines that got higher MPG. The US cars were using an inferior technology that was not strategic: huge pushrod engines, with terrible MPG.
Also, nearly all US made cars had the 3 speed automatic, so engine RPM's were high and noisy at high way speeds.
But I wouldn't mind getting some 1970's Ford LTD products if I could find one in mint condition.
I've looked on Craigslist, found some in good condition, but nothing mint. I'd rather pay more for a mint one with low miles,
then to get a beater with worn seats, fading paint, etc.
