When I first saw this thing on Autotrader, I thought it was some awful kit. But turns out, it was an actual thing. The Tojan was built by Knudsen Automotive for GM to run with the Ferrari and yet be affordable for the every man. Ya. It's pretty much the same as a Ferrari. Mmm-hmm.
At any rate, with only a few hundred made, they are very rare. On the other hand, supply must be paired with demand for a thing to have value, and I can't see anyone wanting this. But for $3900, it might be worth it.
