MPG war! Who's got the best HWY MPG?

I'm going to see if it does any better or worse on the way back to Dallas.

My work commute is only 10 miles of half city, half backroads and average 19-ish. Hard not to blow out the cobwebs on the backroads, so mileage suffers for my sanity.

My SL55 does 21 mpg on highway cruise, and 15 around town. Not bad for a heavy 500 HP monster that I can't keep my foot out of.
The E350 Bluetec does 40 mpg on cruise, and about 32 with me wife going shopping.

Might pick up a w123 240D for sitting in traffic next year. They have no power but how much do you need for traveling 15mph on the highway at 5pm?
