me neither, and i've checked pretty extensively. $7500 for a decent one is a good price for here in the ba.
you'll find they handle much better than the 911's. you'd have to pay at least 4x the cost of a 951 to get a 911 that handled as well on the track. and for only about $5k in suspension mods, the 951 will pretty much take on any production car on the track.
good luck in your search.
