just been and got my first benz ml and wanted to know if i had anythin to worry about from reviews i read my 2006 ml 320cdi seams to be pretty reliable only had it a few weeks know but seems to be a great 4x4 for myself, partner and golden retriever, just wondered if anyone new whether you can use the car in manual like i do my 2011 smart as the ml does have buttons on the back of the wheel.
