OK, so I'm a sad git with nothing beter to do with my time!
Now that I have a 3 Series, I tend to notice them - as you do. I can spot M Sports from SEs by the bumpers and wheels, 6 Cylinders for the tail pipes and so on. BUT, I have found no logic (with the exception of an M3) as to if you get a smooth bonnet or one with ridges on it - put me out of my misery please
