first you should check the market price on your area! see how much everybody is selling these boxsters for.
also a boxster with over 100k miles and with unknown service record i think you might need pay more than 20k after you fix everything just check other posts on this forum.
i am not trying to piss you off, but some post looks like a low baller that most likely are not welcome.
