Thanks John, not overly concerned about 29mpg at 75, I'm enough happy with that, and would expect around there. It just strikes me that 19mpg city driving may be a bit low, considering the 330 and the M3 did better mileage on the same route. But it quite possibly could be due the them having more modern engines.
