There's what appears to be a '75 or '76 280Z on mythbusters on discovery channel right now (8:06 Central).

Dang i missed it...

Ill catch it 11 pm ct

It wasn't as good as I hoped. They're raceing a matchbox against a real car (by gravity, down a 1/4 mile). They were working with a 280Z during early design, but then the FOOLS switched to a Viper for the actual race :surprised

I've seen that car in a few episodes. It lurkes in the background on the new episodes. They were driving it around on the runway with a few other cars at one stage, so it leads me to think it belongs to one of the cast or crew.

AFAIK it belongs to one of the chicks on the show.
