An E55 bone stock is definitely a handful for a chipped and pullied Cobra as the vids showed. Of course, at over twice the list price of an '04 Cobra, IT SHOULD BE!!! (However, the driver of the Cobra seemed to have some difficulty shifting - he needed to drive it like he stole it to have a chance against the 5 speed auto that is purpose built in the AMG. But, it sounded almost like he was not powershifting the car(?).)
Good vids - thanks for the links!
