I was under the impression after around 2008 most manufacturers did away with providing any means to add a conventional block heater. I have only heard good things of the cold start abilities of the 211 even in the most severe of Canadian conditions. I still have a hard time believing it but have witnessed it with diesel Mercedes, fords and dodges.
