there's loads of nice stuff on mbspy about the suspension changes to the new e's including the standard air suspension and adaptive shocks on the new 500. Sounds like alot of trips to the dealer for the first year buyers. The braking system is removed from the driver somewhat, with an artifically produced 'brake feel'. One wouldn't be surprised if the the brakes at some point are voice actuated. There will also be a voice activated nav system which should be fun/frustrating .
