Waited 10 yrs to responsibly afford this car. WELL WORTH IT. My wife and I treat this vehicle like a family heirloom. A recent VA-NY road trip was blissful... too short even. Getting acquainted w/ the onboard systems is a fun adventure. Upgrading to the 2009 S550 4Matic (from our 2000 E320) was like being selected from an overcrowded coach class seat by a pretty flight attendant and being led by the soft, well-manicured hand to posh first class seats. Straight forward power is embarrassingly obliging. Leather, wood and interior touches are like a private men's club lounge that even a discerning lady can appreciate. Play it cool on long runs and flirt w/ 30 mpg. NY ice/snow: no problems!
HK sound system: Clean, responsive bass. Love the heated/cooling seats. Love the feel of the leather/wood steering wheel. 4MATIC feels so sure footed ALL THE TIME, not just in snow/ice/rain. Show room black paint is a pleasure to keep like a mirror. Love the center console "arm rest". Love it!
I'm sure this vehicle will be expensive to maintain, but we waited till we could not only afford the car but also the unexpected maintenance costs. Wish the city mpg was better. Wish gas wasn't so expensive. Don't believe Mercedes could've done much differently to please us. We're very smitten!
