You have to give credit to any high-end sports car (Porsche, Ferrari) driver who takes their car to the track, regardless of how slow they are compared to the berzerkers wringing the necks of their peasant cars. They are at the track, utilizing the cars in the way that they were intended. I never sneer at a dude tiptoing their 997 twin turbo around Watkins Glen at 2:40 per lap: at least they're there. It's sadder when somebody buys an Enzo just to park it at the cricket club. The other nice aspect is that we can leave the track knowing that, by driving our MINIs at the ragged edge of our ability, we were quicker than the dude in the $100k sports car. BTW, I have been that guy--the guy who smashes his car into oblivion at a track event. It was embarrasing, traumatizing, and potentially it could have been fatal. It forever changed how I approach a track day. Whatever car you are in, it is smart to approach a track cautiously, and build speed and courage as you go. In autocross, I recommend that people overdrive the course first, hit a few cones, and dial it back from there. In HPDEs, just the opposite.
I don't sneer at them, but I guess I don't get the point. Why buy a 130,000 GT3 when you can get something as nice (at least on the inside) for 1/3 of that? They're leaving a ton of car on the table, at least from a performance perspective. But then again, I never "got" Hummers either....
