Do you miss ABC on you '07/'08 S550 4-Matic?
Drove an '07 S550 Launch Edition w/o ABC and would argue handling/stability was rather scary, even at legal speeds on typical urban roads/fwys (S550 and CL550 w/ABC are far superior).....suspect Airmatic is a suboptimal/antiquated chassis...perhaps acceptable for guys who typically drive SUVs and other low-tech/non-perf vehicles.....
If were stuck in NYC/Chicago, would prob opt to get an S550 4Matic for yr-round use (5mos/yr need winter tires/wheels anyway); carefully drive at speed limit on all those boring, often straight, roads w/rather slow traffic flows that characterize those urban regions.....and simply get a wkend place in LA/SF to keep/drive more interesting cars....for more entertaining drives on roads w/much more interesting topography, traffic flow speeds, weather, etc anyway.....
