65 promotional car?? test car? HELP

I ran into a guy I knew in high school the other day. He owns a tow truck now. We got talking and he starts telling me about this guy near here that has the Cuda prototype. Some old guy too who swears this thing is a the Cuda prototype, so my friend says. My friend claims to have seen it, but doesn't really know Mopars. He says the old guy has a 1920's Bugatti sitting behind it too!

He told me where to go, when I have a day off I'll be going there, it's about 20 minute drive from my place, but I suspect it's more likely the old man's prototype cuda, not Mopars prototype!
