I had the touring, recently sold at grassicks perth as an approved used bmw with 2 year warranty, whoever bought it will certainly need it.

I loved the car, only downsides were the gearbox and the fact it would cut the power mid drift if the foot brake was applied. For most people driving style/skills it wouldn't matter. Gearbox was good when flatout and did what you told it up and down the gears. I'd have prefered manual but not available.

I had a few problems, most down to hard use/abuse.

As for fuel, possibly the worst car I've ever owned on fuel. My average mpg over around 10/15k miles was 9.Xmpg, 15mpg on a decent normal run. Usually hovered around 10/11mpg in town driving. A fast run would read 7mpg which is as low as the mpg calculator would so probably worse. So to sum is crap on fuel but to be expected on a car that easily does 200mph.

As for the original question, M3 no brainer. V8 M3 is alot better on fuel than the M5, average 18/20, 24/25mpg on a run. Obviously these figures are alot worse if driven hard everywhere.
