Correct Em, they have an uprated 4.6 Alpina tuned engne, side pipes, brake ducts, carbon roof, carbon interior, and semi-slick tyres with a different wheel colour and perforated leather interior, a custom steering wheel and probably other bits I have forgot.
They were also built off the production line by Aero racing (I imagine part of the homologation rules as Aero racing was setup to be a separate entity from MMC to protect them from the racing), I believe they are lighter due to the roof as well.
Only 11 built, but for some reason #1 (the car I am questioning above) was built with a different body - although it appears almost invisible!
