Please do. But from my own observation in E90 MSport 320d and F30 MSport (without adaptive suspensions), I can tell you FOR SURE, the F30 is way more comfortable.I like the E90 design more than F30. It has a design of its own, just like the E46. Will feedback to you guys after i test drove F30. Haven't have time to try one.
This article is VERY informative on e90 vs f30 with actual measurements.
