So? An E60 M5 also costs a lot more to buy and run.

I'm expressing an opinion, nothing more. I don't want E60 M5 levels of fuel consumption from a Vauxhall Omega Coupe any more than I'd want to pay steak restuarant money for a pizza hut.
And I quite like Pizza Hut, in the same way that I quite like the Monaro.
