Hm. To each his own, I guess. The looks of the Boxster are probably last on the list of things I would list under "positives." On the other hand, I absolutely love the looks of the Corvette, both vanilla and Z06. Nothing more than personal preference really.
Wheels are easy to change. A nice set of CCWs would set the car off nicely. At least Chevy spent the money to equip the car with factory wheels that are strong and light - unlike Porsche, who chose to equip the Boxster with 30+lb wheels, with the exception of the lightweight 5-spokes like you have.
I love the feel of the car too, that's why I chose it over a C5 Z06 which would have been an awesome competition car as well. Excellent, just different. The Boxster is hard to beat; it has a vice-free chassis with neutral handling from the factory. Absolutely brilliant for a car with four struts.
