I have. I've even questioned the trip computer. The one thing I did find out is ours is an in-between model that came out before Bluetec was in place with the catalytic-like converters (or whatever they are - Urea systems, I think they're called) on the exhaust system. Not having them accounts for better mileage and more power. The dealership says our mileage is entirely possible. Mercedes just says, "Yah!"
