Thanks everyone for all the useful information and kind responses.
I am about to place an order but came to know yesterday that F10 is subject to facelift for year model 2014 not 2015, which means that product for 2014 would start hitting the markets late this summer!!
To me this is surprising, since BMW would introduce the facelift after completing 4 years and then change the design after 3 years of the facelift. 5 series F10 has been introduced as year model 2011 !
I have reached out to our dealer for confirmation but still waiting the response.
Anyone can comment on that or share some validated input please...
