I forgot all about the suction-cup Garfields. "Baby On Board" signs were popular for awhile.
I remember a lot of stuff in neon colors. Windshield wipers, particularly the two-bladed wipers, in neon yellow or green. Some people had neon bandannas they had tied like a headband and hung from their rear-view mirrors. Bonus points for having buttons from various bands pinned to it.
Yesterday was Fierorama so in honor of the 80s I wore my white Reebok hightops, the kind with the giant tongue and padding around the ankles. They look good but hurt my feet since the soles ahve kind of petrified over the years but they're VERY 80s.
EDIT - SCCAFiero beat me to it while I was typing!
