Considering you could only really exercise it on a race track, it might make more economic sense to pick up a cast-off Nascar road race chassis and motor for 50 grand or so. Plus if you do lose it going into Canada corner @ Elhart, it’s much more likely you’d come out unmaimed.
I once got to drive a Porsche from Nurnburg to the French border at 2 am on a weeknight. I stayed at 140 most of the time, and was passed by some faster Mercedes in the Spessarts.
There’s NOTHING like a Porsche.
