I noticed on Rennlist a chap recently sold his 964 RS America for $22k.......now with the £/$ having recently been in the 1.98-2.00 range, this starts to make sense for a track day 911.
I appreciate an RS America is not quite a halfway stop between a regular C2 and a real deal RS (even lsd was option on RSA [:-]), more a lightly fettled C2 in fact, but certainly has me thinking at that price? []
