Costs about $800K USD, which is a few tens of millions less than the real thing. Apparently you also see the GTO cars racing in the classic races, as a stand in when the owner owns the real thing.
As an aside, I think the 250TR is one of the absolute prettiest cars ever built. Prettier even than the 250GTO. I'm equally unlikely to own either though.
He did track days with it, and set very respectable times. (He also raced a 1969 Ford Mustang in the local historic class. He was a fairly fast driver for a club racer. Not professional race driver fast, but he certainly wasn't babying his cars.)
