I used to own a 99 MX5 Miata for 4 years. Compared to a Boxster I consider it virtually bulletproof. Now I have my 2001 Boxster 2.7, I am prepared to spend $$$ on it if I have to. For me it is worth it. The Boxster is not bulletproof but to me it is well worth the driving pleasure. Do the research. It is a depreciating asset over here.
Dont rush into making a decision. Pothole sounds like a great potential help. I can say good luck but you make it luckier if you do your homework with pothole. Enjoy the search and enjoy the ride
Try lots of Boxsters but mind u I bought the 2nd one I tried. It was a good one and still is.
