I dont own one but I did drive one at brooklands for the day. I did get to give the SLS an absolute hammering. I have driven a c63 on the road and before they let me loose in the sls they gave me an SL63 as a marker. The difference in performance is significant, I think the extra 100 hp really makes the difference. Its an easy car to drive fast or pootle around town at low speeds. I wouldnt describe it as nimble and the bonnet is long. I think its a great all rounder and would consider one if I didnt have a mortgage,wife and child. If you are considering one, the sls day at brooklands is prob a good idea. My instructor was very good and we tested all the settings and technology onboard to see how the car drives differently depending on how you set the car up.
