I know the 35i can get very good fuel consumption. Stating the obvious now, but depending on the way you drive it can vary a lot.
The way I drive, I don't really pay attention to the mpg and I think the performance/economy of the diesel suits my driving behaviour more.
As in I probably appreciate the torque and economy more in the diesel over the performance and sound of the petrol, 99% of the time.
EDIT: But still no one getting a 35i?
