1. Great balance between comfort and handling
2. 50/50 weight distribution
3. RWD (even though I liked the Quattro on my previous AUDI there were times I felt it was a waste dragging around that extra weight of AWD)
2. The 3 series sedan has been on the best buy list of any car magazine (car& Driver, Top Gear etc..)
4. The interior layout is simple and effective (even if you move from one model to the newer you still feel at home with all the controls)
5. What others think about you (ex. BMW owner - young professional, Mercedes - Old rich guy)
