Tomc88, You've bought a goergous example! The wheels are from 'Porsche Sport Design', a slightly separate part of Porsche that is, as I understand it, an industrial design firm and therefor design everything from watches to office furniture. From what I've been able to gather, they design a new wheel every year and when a customer orders a car it's available to them as an option. They are 2- piece wheels and I read somewhere(?) that the bolts are titanium!
Many of your comments mirror exactly how I felt when I bought my car- your first Porsche is truly a SPECIAL experience and the driving part is the best part of it! I tell people that I bought mine because of how it drives but they don't get that unless I let them do so too.
