marmer, I have to apologise to you, because it turns out that I had misinterpreted my information. The name I was looking for was Zoemo Leaju, but Zoemo is just one of the myriads of makers of customised interiors for luxury and executive vans that works with various suppliers. The fact that Zoemo proudly displays on its website that they are a certified Mercedes Benz partner doesn't mean that they build the vans; it just means that they have passed a quality examination and are allowed to modify the vans and still retain the Mercedes warranty.The Leaju model is just a JAC Sunray with a more luxurious interior by Zoemo, and a new badge. So you win the point for correctly identifying what it really was, and again, my apologies for the confusion and the extra work. Well done!
