If it was a supercar it would not be expensive, but for a supercruiser its a rip off, unless you place value on the "image" of the car, but we know what thats called

The difference is that you think of straight-line acceleration as performance, and thats fine, but others regard the handling, track times, involvement and raw sportcar character as the performance. Straight-line acceleration is easy to obtain, the other more difficult, and is what characterises "supercars" and differentiate them from the high-end sportcars. They go out of their way to use lighweight materials for low curb weights, low center of gravety and low polar moment of inertia engine placements, developing high output out of atmosphetic high-reving engines, involving transmitions-steering-brakes and optimun gear ratios, highspeed aerodinamic aids, ect. If straight-line figures and top speed is the only thing we consider when comparing it to the other supercars, then drop the SLR's engine on a SL and it will be just as "fast" in straigh-line, were is the merit of the SLR then?

Straight-line acceleration is amusing the first time or the second, the third time I'm starting to get bored. For Euro 13-14k you can get a gixxer that will that will out accelerate any supercar, is that the most amusing part of the bike? no. Would I trade a 30kg for 30HP more? no.
