the merc slr mclaren is a disgrace to the mclaren name. the car is made up of carbon fiber and still weights a porky 3700 lbs. the car has the most useless stuff in it such as a computer controlled brake system. instead of using traditional hydraulic brake master cylinder that is directly linked to the brake pedal. now the computer tries to guess what your tryin to do, and it leads to a really jerky and not smooth braking action. not to mention it adds more weight. the germans didn't let gordon murray have any of his ways. gordon murray was soo frustrated with merc that he even didn't show up on the debute of the slr.
