I switched from an 03 BMW 530i. Yes I gave up a lot of interior room; but thats it! I gained so much more when I purchased this vehicle. It's faster, more reliable, better looking, fit and finish is worlds apart from BMW. Did I mention more reliable; so long to numerous trips to the repair shop. I am really enjoying this ride!
I like the park assist (no more guessing in the garage) the headlights. I also like the auto-dimming rearview mirror. I average about 23.5 MPG so far, which is not bad for the performance. The perforated leather seats are cool too, no pun intended. My passengers like the cool air on their bums.
I think navigation and the mark levison upgrades should come standard on these vehicles. The suspension could be a tad stiffer as well. No real complaints!
