Not everything in the 1970's sucked.
From 1971-73, Ferrari made 122 examples of perhaps the most desirable car to ever travel the earth: the 365 GTS/4, also known as the Daytona Spyder. An open air V-12 front engined car that personally, I would take over any other car ever produced by Ferrari. Or made by anyone.
Chevrolet replaced the Camaro with the Gen II model in 1970, and what a move forward. Sure, it still had a live axle in the rear, but the chassis was 100x better than the outgoing 67-69 models, and the new Z28 was fast of the floor, and with not a lot of work, could be made to run a road course with some pretty big dogs. People lust after the 67-69 models, but the 1970 was a much better driver's car.
Porsche dropped the now-iconic 911 turbo on us in 1976. The Big Three has begun to neuter their V-8s and it looked like performance was dead. Then Porsche said "no, it ees not. We use zee turbo thing and make zee car very fast."
In 1975, Mercedes introduced the 70's version of the Muscle-Sedan, the 6.9. While I'd prefer to own an earlier 300SEL 6.3, the big 6.9 is a thing to behold.
In 1978, Bruce Springsteen sang "Racing in the Street." For those of us that spent a lot of effort to make our V-8 muscle/pony cars appear NOT fast for strip/street nights, the song was our anthem. Thanks to the many 5.0L Mustang owners that were victimized by my small-block Camaro, and the bankroll they padded. The most complicated thing about life was tuning the Holley...
