Thumbs up there, ProjectM96. Looks like you have yourself a decent car, all right.
I have to agree with Pothole to a point. There are many more cost effective cars out there than the Boxster, so it would really come down to how much you have your heart set on a Boxster than having your heart set on just getting a fun roadster. There are Miatas, Z3s, Z4s, SLKs, S2000s, or even the Solstice/Sky, all of which will fit the bill and be enjoyable to you if you find one that appeals to you (both in appearance and how it drives).
Now if you're set on a Boxster, go for it, and as you'll hear from advice given here time and again, get the youngest one you can afford, and get a pre-purchase inspection no matter what. You won't be disappointed, and if you can wrench it yourself or have a good buddy willing to dive in there with/for you, you won't be dumping money into it like you could.
