Real world M6/M5 fuel consumption

[kazino]

I'm torn between a 996 turbo and an M6 and so far the stories of eye watering fuel consumption are putting me off the M6 as I intend to use it to do euro trips and I don't like the idea of throwing my hard earned on fuel.
Could I please have your real world figures for :

motorway driving i.e a steady 80mph
London city driving
B road blasting

What I've heard so far is you would struggle to get 20mpg on the motorway, struggle to get 10mpg in town and looking at 5-7mpg when hammering the car. If this is the case I don't think I can justify the car unless I marry a Saudi princess tomorrow

I did indeed and that is what inspired me to ask the question I was expecting it to be much worse than that. However I don't know what the majority of the driving would be on that car, it seems like it is quite mixed and if so might turn out to be more economical than I thought.

Thanks for the advice guys, I'm a great fan of the 5.0 v10 and the practicality of the M6/M5 but I know it's going to be stupidly expensive to run in terms of fuel and servicing which the 996 turbo won't have. I'm in love with that engine though, can't get the sound out of my head after the test drive.

What an amazing car. Just don't like the idea of being putting off driving the thing due to the insane fuel costs when hammering it and I like to go out for drives.
