I was lucky enough to be in high school 91-94, and college from 94-98.
What sticks out in my mind in the early 90s (regarding cars) - 225 hp in a Mustang 5.0 was something to brag about (and be feared), I remember the low rider pick up truck phase, when neon lights under cars first came out, when a cell phone was in the form of a bag phone, when "hammers" and "five stars" were
the wheels to have, I remember when an Alpine head and Jenson 6X9's (along with some kind of a sub) constituted a "system", and when guys would play their Sony Discman thru the head unit, because not every car came with a cd player.
EDIT - and I forgot to mention the "blackout kits / covers" for
headlights and taillights.
