I agree on the roof, nav not so much. It's not that I use the nav (I have never) but the stereo upgrade on this car is impressive if you look at the build. Unless I'm tracking my car regularly or it's an old car I always want a good stereo. But different strokes for different folks.

At the end of the day this is still an M3 and there is no downgrade here (ie. regular 911 vs S or GT3) so the experience is exactly the same. The car makes great noise, handles and accelerates incredibly, and is an amazing car overall.
