The CLS is fast for what it is but not very fun, IMO, to drive. It would do well I think here because stock tires are meatier than the C63 and big power. However, it isn't as responsive, fun, controlled or as nimble as the C63 (which is less nimble than the M3) in my experience. Still a very fast car though. I know the only way to truly compare is stock but with better tires on the C63 (rather than 235/255 Contis), it would have been faster IMO than the CLS63. It certainly "feels" faster and is MUCH more fun to drive on the track.
