I bought a tbss thinking it would be the best of all worlds, but I ended up being miserable in that thing. It was only average as a performer and average as a utility. I'm sure a Cayenne Turbo beats a tbss at everything, but I learned to always buy one car/one purpose. Plus, spending $85 every 225 miles got old real damn quick.
You've got other fun cars, so whatever, but I would personally not buy a "performance" suv again. Just my two nickels.
