Local/town etc. 38mpg, motorway typically 47/48mpg on a good run, have seen 50 but that was being a bit too sensible.
It's my third S211 estate and the best all rounder. I found a nice late 2008 Avantgarde spec with memory & heated leather seats, Command ntg2.5/linguatronic, parkassist. And I like the ride and comfort of the standard 16" alloys.
