The Metris has been in North America since 2016. Its been in Europe a whole lot longer, with recent versions marketed as the Vito, Viano, V Class and the Marco Polo, which is the much more upscale camper that what you see offered on this side of the Atlantic. In Europe you can get a diesel engine and 4WD. Here in North America the Metris is just offered with a gasoline engine (M274) and rear wheel drive. There is now a longer wheel base option also.

I currently own a Metris that is converted to a camper. It fits in a standard garage and is a great vehicle to drive. But, its made by Mercedes so the parts are expensive and frequently hard to get.
Like every thing in life, there are trade off. It has a long wheel base and is quite low. A 2" lift kit will help a bit, but you won't be doing any type of off roading like the bs picture in the article. There are not a large number of Metris dealers around so getting warranty work, or even routine work is a problem. Like the Sprinter, they are sold as commercial vehicles so if you think you'll get assistance from an MB auto dealership you'll more likely than not be sent on your way just like any Yugo owner that hoped for assistance.
Did I mention that parts are expensive and frequently hard to get? Which is why I will soon be selling my Metris.
