ACR Joe - was the 2008 JCW a limited edition like the former two seater? That limited edition was a really neat model.

In the last generation of the Mini, the John Cooper Works package underwent a slow evolution. It began as a dealer-installed kit that included a revised head, a new supercharger with a smaller drive pulley, and a free-flowing exhaust system. The sum of the parts was a 37-hp bump to an even 200. Eventually, the kits became so popular that they were installed on the assembly line. For its last hurrah, JCW created the Grand Prix kit, a limited-edition model that deleted the back seat in favor of a strut-tower brace and boosted the horsepower to 215.
