8 track was a brief step up for my brother, who started out with a car LP player.
As long as the road was smooth (recently re-paved preferable), it almost worked. You could almost see the vinyl being carved out of the grooves...
The 'reverb unit' that was previously attached to the Chevys' dash radio was absolutely hilarious, tho'...
Hit any bump, manhole cover, or debris rewarded you with a loud "BOIIIINNNGGggg" that would make me laugh like a hyena while he'd get pissed.
The follow-up 8 track was a great respite to all that....until the tape would stretch and I'd get relegated to digging it out of the player.
After losing a few carts, he'd moved on to the 396 Chevelle, whose engine and exhaust made more pleasant noises..... ;)
