Wow, I've never driven one. I would expect a bit better than that too. Of course, there ain't a whole lot of 'em doing 55. Most around here seem to hover in the 80-ish range!

I think one overlooked advantage is the selection of a good tire. If you stress least rolling resistance over off-road grip, it will indeed help with mileage. Plus keep them inflated correctly, something a lot of people don't do.

Maybe I'm just lucky and got a very rare 318 setup. I guess I'll keep it another eleven years.
