these cars cant even be compared. The SLR, is an amazing Super-Sports car while the SL65 AMG is just a high powered saloon type car. While the BHP is close within 10 give or take, i doubt the SL65 will have the low weight, extremem handling and amazing brakes. To put the SLR in perspective top gear tested the Zonda and the Koenigsegg around their test track, same condiditions with the same race driver and both clocked in at around 1:23:xxx (remember these are out and out sports cars, no comprimises, and the enzo is about the same round the track as these 2). Then the SLR, clocked a tme of 1:20:xxx. 3 seconds faster which is stupidly fast!!..At the moent no car compares to this as it is amazingly fast round a track in a straight line, very well refined, and eve has a good sized boot. This car is amazing!!
