Especially since that vette is like $45K less (as tested) than the GTR. However both of them are highly complex machines that will have significant cost of ownership to keep them in reasonable condition. The GTR though is a total tech wonder that I think will cost far more than the vette in care and maintenance. Of course, that is total speculation.
Buy one, own it for a year,
the sh!t out of it, and sell it. OK maybe two years since you have to get the driving value out of the first year depreciation.
