It's been done.
that's still a commercial vehicle though. This is looking like they want to enter the Ridgeline / Tacoma / Colorado / or even full size market (not sure of size by the capabilities listed look mid-size)... I just can't picture too much of a market for a MB mid-size or full size truck.
People already say mid-size trucks are expensive. Can you imagine the increase price for having an MB grill?
again, I don't know who would buy that.
