PCD doesnt save you much money becuase you pay the US delivery price. however, you do get a tour of the factory and driving lessons in a car similar to yours. i think as of last year, you can do both ED and PCD which would be amazing but it woudl probably take forever to get your car so you cant be in a hurry haha
btw bimmerfest, i must say, is a great place to go when looking to buy a new car. they have the best collection of info with regards to this topic
yea i got mine for 1000 over ED invoice... before all the price increases so e92 335i, sport, premium, cold weather,comfort access, and usb for under 42k
as for wheels those new vmr v710 look nice. if i upgrade wheels they better be lighter than stock, however.
