Probably because you are in the unfortunate position of being about the 5th person this weeks to make a similar post, and the forum is going through a bit of a "recharge"...
Make use of the "Search", many of your questions have been answered before, also there are a number of good resources on the forum & the interwebs in support of these cars.
Mike Focke's is an excellent one:

Also the forum's sticky thread:

Keep in mind, there is a saying around the community that "There is no such thing as a cheap Porsche" -- if you're planning on buying a 10K Boxster, without planning a few thousand a year in maintenance, you'll have to be fairly lucky to have a running car in a few years. There are many things that can go wrong (search IMS, RMS, water pump, AOS, CV boots, ...)
It's not that they are crappy cars, but the average 986 is over 10 years old, and many sit for long periods of time without being used. They aren't Camry's in terms of maintenance.
It's your choice on dealing with the IMS Bearing -- The general consensus is there is a small chance of it happening, but enough to make many of us nervous. The potential downside is grenading the engine, making your 10K worth maybe 2K as a roller; budgeting 3K more and getting it replaced is a decent insurance policy, but still no guarantee...
Good luck to you, and if you do buy one, you'll love it!
