I'm currently looking for a 3 series Touring.
I believe the model I want is referred to as an "E91"
THIS is the exact car I want (but it is sold), on Auto trader I can go in to the 'spec' sheet and see this model is the 177bhp version, M-Sport trim, 0-60 8.1 and most importantly 46.3mpg (Urban).
I have deduced that the 177bhp model gives the 46.3mpg figure, whereas most other versions are are much less, except the 1.8, but that is slower acceleration.
Question is, when looking on other sites (not Auto trader) How do I know if it's a 177 model or not?
