It depends on the actual dealer and on the model of car. Some will provide them like on my ex30, they come as standard being the ultra trim. On other cars they haven’t and some dealers have included them as they do a tank of fuel or some charge you for the fuel. Others just don’t, unless you haggle with them for them.
I have a mach e loan car, it has no mats, it doesn’t really matter as I don’t own the car. Although I had one last summer and it had a hole in the carpet near the peddles. So if that happens who’s fault is it and would you buy that car used if it did. So should MB be including mats as they do metallic paint, which cost more. To protect there asset.
