Do you really need AWD? Also, do you want firm or soft suspension? If you want firm, the only choice is F01 RWD.
I would recommend staying away from anything pre-LCI, as well as early build 2013 if possible. On LCI RWD models, you also get EPS instead of hydraulic. It actually gets a bit heavier when you put it in Sport (chassis) mode, plus it's one less fluid to change, leak, etc. As Jay mentioned above, xDrive transfer case problems are expensive.
