Congratulations.
You definitely need to put some more miles on that beauty and enjoy it!
I too am reluctant about selling my Boxster. It's a great car, and I will miss it when it is gone. I am already past the point of no return though now that I've bought 'the next Porsche'.
Right now I can only afford to be a one Porsche kind of guy so the Boxster must go. If circumstances were different I'd keep the Boxster as my DD and take the 993 out for weekends and driving events.
