1st long Roadtrip @ 30.3 mpg ;-)
With that said, I have just gotten 36 MPG on a short highway trip in my C250 (cruise control only set to 60mph). I expect/hope that this number will increase after the break-in period (as it did on my previous c300 4matic - only at 100 miles now) and also when there is warmer weather than 13 degrees!
I reset before pulling out of the driveway, and have about 7 miles of city/backroad driving before I hit the first on-ramp, and I did not pull over or stop once prior to getting that reading in the Richmond area, still driving actually when I snapped that pic.
I wish I would have thought to check it after the whole trip down and again upon return - but I let my brothers both drive the car while I was down there and they both "had a blast" with it, which I am sure killed the MPG (unless 125mph on route 26 heading from Summerville back into Charleston yeilds 30mpg also...I think not)
