I completely agree about the green aspect; it may be able to run on biofuel, but it's still going to use a lot of it! I think your comparison to the SL65 BS is very interesting, but I just can't get over the weight issue. The SuperSports weighs about 2.250 kilos, and that's rather a lot for something purpoting to be a driver's car. The Black Series is almost 400 kilograms lighter, at a still pretty portly 1870 kgs. I just have a hard time seeing the core appeal of a car that costs a third more than a Conti GT Speed, with no usable back seats, manual seats, and a weight of more than two metric tons. You're probably not gonna get GT3 RS-like handling...
Regardless, somebody's probably gonna buy it. I wonder if any countries have any kind of tax exemptions for bio-fuel compatible vehicles?

 

Thank you! I'm going for training on the SuperSports and the Arnage replacement. I'll post pics when I return.

 

Wow, that really sounds amazing! Looking forward to pics!!!!
