I agree completely. It would appear that original purchasers customized these cars,and some quite uniquely during the order process.
I have an S, very lightly optioned, but with DSP?! I guess the original purschaser was a minimalist, but wanted the best possible tunes available at the time.
That and colour choices too... A bit over a year ago, I saw a Guards Red Boxster for sale with a Metropol Blue interior.

The dealer was touting it as a rare colour combination. Yeah, right. Just painfully horrid to look at is more like it.
On the other hand, your Arctic Silver/Nephrite Green combination is rather cool. I'm digging it. Now go out and drive it already. Make up for the guys like me that hibernate ours for the winter!
