Me and a friend went around town with this on my car. Most people looked at us like “Oh my god, I can’t believe it!” or “Alright!”. The only guy who wasn’t laughing was some dude in a Cavalier with a big fin on his.
Cardboard, dowel rods and duct tape made the fin. Cardboard made the ram intake.
It was for fun. I really don’t care to do something like that for real. I kinda like the Euro-style tail-lights, but that’d be about the only thing I’d really do. I want to replace the speakers with something better, and maybe the deck, but I think the speakers will do more good for the sound-quality than replacing the deck.
