im not sure what kinda white it is. ill find out though..as far as the room in the backset..lol doesnt matter much to me since i will never be sitting back there. i have 2 young daughter who fit back there fine. only 2 seats in the rear so i better be careful if you know what i mean. and yes trust everytime I park I think i turn around and look back the whole way before i get to the elevator at work. this is car is GORGEOUS.. i have had so many cars in the last 15 years my friends say u know your only keeping that thing 6 months..I dont think ill ever let this one go..like i said before good luck to all u BMW guys, but it was just time for a change.
