For those w/ GT3s consider urself lucky!
I was trying to get my hands on a 2008 GT3 for someone from the fleet manager at the 1st or 2nd largest porsche dealership in the U.S. For the 2007 year they were allotted 12 GT3s and 7-8 RS. That's quite a few and they did not charge over MSRP. But for 2008, they only were alloted TWO. That's not very many considering how many 2007 they had. He said there just not alloting that many to anyone. In addition they r selling for over 25k over. Something they rarely do, but because there r so few, they justified it. I guess they r not making that many. If you have one consider urself lucky. I truly believe they will hold their value.
)...relatively cheap MSRP cars; loyal following of used GT3 buyers; and somewhat lim (for P) prod vols....and the Luddite GT3 gearbox prob has much nostalgic value for the boomer buyers.... 
....high-end sportscars were prob proxies for Viagra, hair transplants, plastic surgery, etc well before many such therapies were invented/proliferated; and GT3s/Scuds, etc will likely continue to be adjuvant therapy for many elder (and younger) drivers/owners searching for an "image"....
