New F10 535d is the most frugal of the 6 pots though. 299bhp and 44.8mpg combined is quite tempting, albeit out of the price range of the OP.bloody happy with my 520d thing, amazing economy, had it chipped and its not remotely sluggish, not going to set the world on fire but 850 miles from a tank and very decent performance have provided me with everything i needed from a motorway muncher.
if fuel costs are a concern I can't see a 535d being the answer![]()
