2008 Mercedes-Benz E-Class E350 4dr Sedan (3.5L 6cyl 7A)
I now have a little over 3k miles. Very responsive on the road. I like all the features. Tried other cars like the BMW 5 series, can't compare. This ride is smooth, great sound system, and surprisingly good gas mileage for a v6. I'm very happy with my first MB.
Adjustable & heated seats. Lots of storage in the trunk and convenient hidden compartment under each seat. Gas tank locks and unlocks automatically. Best is if you hold down the lock/unlock button, it rolls the windows up or down in sync.
Better iPod controls to switch between songs, artists, and albums.
