Interesting, thanks for the insight.
First and foremost it will be my daily driver. So fuel economy is pretty much the only thing that's putting me off the e92. I don't do huge mileage, maybe 15-20km per day for my daily commute, but it's mostly "urban". I've heard and read mixed views on this - some people say the fuel economy is catastrophic, others say it's not that as bad as expected (but I suppose that's relative and depends on your starting point).
I've also heard some people say the e92 isn't that much worse on fuel than the e46 - not sure if there's much truth to that?
