Beanie,
I have not seen prices falling on SPF cars (which are the only prices I track).
You might see some of the older SPFs going cheap, but the ones I am aware of that were in decent condition (my idea of decent) and newer s/n's were well over 40K. hell, my old 992 WITH the deer damage sold for almost the price you want to pay.
A couple of 500 series went 3 months ago for just over 50K, as they had FE motors in them, and those seem to get the best resale price. a 1100 series car JUST sold in St.Louis for 47K, from owner, to owner.
Use a second on the house, join the club!
