Congratulations!
I bought mine last year around May. You probably did better than I on your final price given the current economy. I am new to Boxster ownership but I can tell you a few things about our local area.
I saved a bundle on doing my 30K check at Midwest Eurosport near the airport. They were very professional and did the service check for $375 or so rather than $1,200 which was quoted to me from Napleton Porsche. Midwest Eurosport only work on Porsches and was recommend to me by a friend who races his 944 turbo.
NickCats and Sammy are local Boxster owners and they have invited me to their autocross (first one is April 20th). You should PM them if you are interested.
