I ordered a M-sport X3 last month at beginning of March, still waiting for it to come on ~June. I asked to trade-in the 19" the M-sport comes with, with the 20" M double spoke 310 wheels, the dealer charges me AU$8K (~US$9K) for it!! If it was new (not trade-in the 19"), they charge $11K!!
Not happy with it and turned away!
