Pick up a copy of Excellence Magazine's buyer's guide. It discusses weak spots for each Boxster year and as well as listing a range of prices. Don't ever make a German car purchase without having a basic understanding of the car's weak points. Coming to a forum is not a substitute for this. Also, I recommend buying a 2.7 or 3.2 Boxster with the IMS issue already sorted out.
At this point there are many cars like this out there and forum members are always looking to sell their cars. Start with the Porsche forum classifieds first. Then try private sellers. As a last resort go the middle man used car dealer route unless your state has some lemon law guarantees. This was the case with my purchase, NJ required a 1 year limited warranty for dealer sales....but my car only had 9K miles when I picked it up. When stepping into a car that has seen very low mileage or very high mileage, you need to do some research. Both can have very costly expenses awaiting.
