Honda, Toyota, and Nissan all offered small and economical front-engine rear wheel drive sports cars. A 1967 Toyota Sports 800 is shown parked in front of a 1996 Honda S600 in this image:
Safety, emissions, and a yearn for even more power and handling ended this age. Honda didn't play again for 30 years, however Nissan brought out the famous 240Z and Toyota the ultra-rare 2000GT.
