Have owned E550 for 2 weeks. In shop for last three days. Voice command inoperable ,drivers side airbag inoperable, rattle in dash. Dealer followed MB bulletin, did not correct rattle. Quality still a question after all the QA/QC conferences held by MB. Leased vehicle based on a complete makeover per MB and the deletion of the Bosh electric brakes which cost MB dearly in warranty costs. Wife likes style of car which is better than a 550i BMW. However the adjustable air suspension is not calibrated correctly. Neither the soft, normal, or hard setting provide a satisfying ride. BMW still a better ride and a true drivers car. Sold one of the last 2001 BMW 740i sports to do deal, I hope this was not a big mistake.
Offer AMG suspension on E6.3 as option on the E550.This consists of recalibration of the air suspension and thicker sway bars. Redesign dash to delete bar gauges for oil temp and fuel. Update voice command functions to be competitive with other manufacturers.
