Thats very rough and bad form ... I was told to stay clear of Comfort seats and told the standard 18" wheels were in short supply... meaning I was asked to fork out $1400 for 19" wheels... and to settle on sports seats instead (although it did help make my mind up as I am not that impressed with the look of the comfort seats to be honest !!)... My car is on for May production but I am suspicious.. the dealer reassures me there is no problem with what I have ordered...I was going to get the ML 320 but worked out that it was "cheaper" to get the X5 and also liked the X5 better anyway..maybe I may end up having to go back to Mercedes after all !!
