OP - I'm doing the exact same thing, but I did test-drive a few F30s before placing my order on 12/15. I will miss the power level I have with my 07 E92, but I wanted something a little bigger, which the F30 is - same legroom as F10 5-series but not as wide or heavy. Currently, my plans for mods are limited to Dinan S2 (when it comes out) and probably an ETS 5" intercooler. I ordered the adaptive suspension, so that should be interesting as well. If it feels like a "mature person's car", that works for me - I'm 64, but as one of my T-shirts says, "still plays with cars".
