I'd buy something really nice but not flashy for $100-150K, and put the rest into conservative tax-sheltered investments.

I'd use the yield from the investments to cover fuel and insurance and repairs, and would have enough left over to rent an exotic now and then. That, to me, would beat the heck out of owning one or more exotics and all the headaches and expenses and unwelcome attention that go along with that.
