Hi,I have just given up on 328i mostly due to the average cockpit material + room.It'll be a big thing in my life deciding to own an F10. I do not have the budget for 528i but two things concern me i.e. the missing HUD and paddle shifters in 520i.3 Questions:#1. Without the paddle shifters on steering, does it still make 520i a wise buy?#2. Do most of you the enthusiasts find the HUD a must-have on a 5er? (I wonder are these the reasons behind the uninspiring sales figure of the 520i that AB has a good number of ready stocks and looks eager to find a buyer.)#3. An SA offers a 1% discount. Is this the maximum discount level BMW would usually budge?I thank you for your generous feedback.
