Having your cake and eating it too! The E-Class is the perfect highway cruiser, soaks up the bumps and smooth as butter. The diesel is phenomenal with gobs of torque off the line and still plenty of passing power from 50 to 90 mph range on the highway. Just drove this baby home 300 miles and got get this 36.8 mpg for the trip about 80% hwy and 20% city driving. Mercedes has it going on - forget hybrids diesel is fuel efficient and practical and proven for over a 100 years! Wasn't impressed with Lexus (dressed up Toyota) and BMW lacks luxury and pampering I was looking for (too spartan inside and weird looking outside) Audi came closest with A6 but alas no diesel in US yet! Drive it - Sold!
Premium package goodies and Satelite radio is the Best! No flipping channels on the way home.
Once US standards take effect for cleaner diesel by the end of this year you won't be able to tell at all you have a diesel car except for the great gas mileage. It is still the only car that feels like a bank vault to me!
