I agree with some folks here that the handling feel of this F10 model sort of replicates the Mercedes. From my experience with my F10 535 M-sport, the suspensions still have too much body-roll when cornering, even on merging freeways ramps and I'm disappointed at that especially with the M-sport package. My 08 Lexus IS has much less body-roll than the 5-ser (I know it's two different cars, but I was expecting something close to that). I have thought about upgrading my sways and/or switching to coilovers, but I would not want to compromise the ride comfort especially when cruising long distance. Secondly, the steering wheels felt heavy at first until I got rid of my run-flats and put regular tires (Yoko's all season; great and very smooth ride). Other than those, I'm very pleased with everything else and I have yet to see the longevity of this beauty.
