Believe me, I know not too caught up on attractive annual tax figures and MPGs.....the E39 hasnt stayed on the driveway without all things considered!
It'll be off to the UK either way, judging by lack of anything other than x20d / x16/18/20i here!
I dont know what the budget will allow for yet, but something like a 328i or similar is kind of where my head is at! They fall into the 390 tax bracket while still offering 40+mpg. Thinking that, it or similar is about the optimum for now and going forward.
