I love both cars, I think they are awesome. I just think you'll enjoy the GTI more - I honestly do. And it would be a shame to waste this ridiculous wait and then not get the GTI! 
In all honesty I totally agree, purely from the point of view of wasting this wait it would be a shame. I'm sure the BMW is great fun, and on back-to-back test drives I guess most of us would side with it. However, as an everyday car, I think drisser summed things up perfectly during his extended run.
Besides, these forums need ya' Bear!
