If I remember correctly, the reason why Chrysler never put the turbine car into production was because of the heat that it developed I remember reading about it as a teenager. I believe that Jay Leno has one other than that I have to idea of how many others may still be around. I'm sure that there's one in the Chrysler museum.
Yes, Jay Leno has one he bought from the Chrysler museum the last time Chrysler almost went belly up. There's a few more out there. Harrah's museum in Las Vegas had one. I don't know where that ended up. Chrysler may have kept one still.
