I ordered my E63 wagon in July 2013 and my car is at the port waiting for a ship to make the trip to the USA. I ordered the car the first day that the US order bank had allocations. It was supposed to be a January build.
It really depends on the model and part availability. My Porsche 911 -- which I ordered was supposed to be a April Build but was delayed to a late September build and got the car in late October; I guess the problems are not only restricted to MB as was implied!!My comment did not relate to the desirability of the car but rather to the ineptitude of the manufacturer at living up to reasonable customer expectations. I have ordered many other cars - PTS Porsche RSs, Astons, and other mind-blowingly desirable cars - all with limited production. EVERY other manufacturer has delivered the car as promised. Among the frustrations is that mine was the FIRST one ordered from a huge, factory owned dealership. As is well known, more than a few E63 Wagons have been delivered, some three or four months ago. Mercedes has a long way to go in providing decent customer service. This from someone with an SL55 and a CLK Black Series.
