I also posted this in the R-Class section but it may be relevant to ML owners, too...
Really like my R-Class but side view mirror blind spots are a problem. A couple times I have checked my left side mirror and started moving over into that lane only to be honked at because my side view mirror was unable to pickup the car whose front bumper was almost even with my rear door. Yes, I do turn my head to look but I still miss these guys once in awhile. I think Mercedes went for aerodynamics and esthetics over function when they designed the side view mirrors for the R-Class.
Recently I saw a newspaper article that said most people do not adjust their side view mirrors properly, saying that most people adjust their side view mirrors so that they see the sides of their own vehicles (guilty as charged). The article went on to say proper side view mirror adjustment should not show any of their own vehicle. Instead, both side view mirrors should be adjusted so that as the image of an overtaking vehicle leaves the interior rear view mirror it is picked up by the appropriate side view mirror (The image of an overtaking vehicle on your left would start to appear in your left side view mirror just as it "disappeared" from the center rear view mirror) and the same for vehicle overtaking on the right).
I have since adjusted my mirrors to this new orientation and after getting over the uncomfortable feeling of not seeing the side of your own vehicle in the side view mirrors, it does work well. The problem with the new mirror orientation is when "backing up". Yes, you can adjust the mirrors back to the old "see the side of your car" setting, but this takes time and you then have to re-adjust the mirrors to the "new" orientation afterwards, which can be difficult to do without actually driving.
Awhile back I found a website that might have a solution to this problem. The company is called "Multivex Mirrors" and they offer a "retrofit" mirror that is cut to fit and installed over the existing mirror.
Multivex makes the following claims:
The closest part of the mirror to vehicle operator:
— Is spherical convex, i.e. constant curvature.
— Is fundamentally distortion free.
— Is usually flatter than OEM mirrors.
— Normally provides larger images than OEM convex mirrors.
— Therefore, produces better distance judgment to trailing vehicles.
— Is used to look mainly straight rearward.
The farthest part of the mirror from vehicle operator:
— Has increasing curvature toward it's outer edge, i.e. is aspheric.
— Has patented increasing curvature producing optically controlled expansion of the field-of-view.
— Is used to look mainly into the former lateral "blind areas".
— Virtually eliminates the "blind areas".
The company offers full instruction on how to make a template of your outside mirrors, which are then used to cut a mirror that will fit over the existing mirror without losing "heated" mirror functionality.
They also offer pre-made side view mirror glass for vehicles for which they have already received templates. On their website they list pre-made mirrors for ML Mercedes up to the 2006 model year. I assume that the side view mirrors on a 2006 ML are the same as a 2006 R-Class, but are they the same for a 2007 R-Class or later years?
I admit I am intrigued by this product but wanted know what the rest of you think.
