I bought this car off Ebay from a non-MB dealer Dec 28, 2008. Car had 29K miles. Still has balance of warranty. This car has a build date of March 07. I'm guessing whatever problem history the 06 E350 4matic had was cleared up by the time mine was built. Car performs well and has been reliable since day one. Paint, fit & finish is exceptional. Like the all black look. Paid less than $20K for the car because the market is in the tank and I smile every second behind the wheel knowing my brother-in-law paid more for a 06 Toyota Avalon. I kept my other car a '94 E320 that I've had for 12 years with 100K miles because I just can't part with it. No complaints with this E350 4Matic!!
None really other than it give me the ability to escape in comfort & style.
