GL 450 Gas Mileage
Mine is due in about 12 days so they say. Do you remember what the difference was the break-in period to now?
I am very pleasantly surprised. I also second Jen's comment on mileage improving with age. I believe that as the engine adapts/learns your style the mileage improves.

Thought I would add to my flipant remark above. I really wanted a diesel but here in CA they are not approved until the 2009 year model which will have made the wait much too long. I always thought CARB was shortsighted in that they did not look at the overall emissions per mile with the much more efficient MB bluetec engine and certainly did not look at the overall lower GH gas number. Sitting on the ARB in my county they still tend to look at the individual engine numbers rather than the overall picture. The real winner will be when we eliminate all parafin fuels (on road and off road) that are not ultra low sulpher. Enjoy the ride and especially the 25% fewer trips to the pump!

What a pleasure meeting everyone, especially you guys who made it seem a lot less strange to be going to these types of gatherings because you (Jen) do it a lot!
The average driving speed was 88mph.

At that speed, I'm pleased with the fuel economy of our 550.

Total trip time was 9 hours 56 minutes with all of our stops.
I let my friends drive home as well, and they enjoyed themselves immensely.
