Someone on Fchat in the GT3 RS thread said they produced 6000 GT3 RS. That's a shit load of cars if true.

Porsche GT car demand has exploded in the last couple years, as have Porsche bubble-like prices. Where there is exploding demand, there is exploding supply. Way more 991 GT3/RS cars on eBay than 996/997.

It's certainly not going to help 991.1 GT3/RS prices that the new ones will be better in every way and have the option for a manual.
