Well then if it was me I would buy an older Cummins powered one. What the heck is a VM motori diesel? Lol. I have a duramax and it has proven to be great. 200,000 and all I have done is change the battery's, serpentine belt, and fluids. So maybe the motori engine is good to. Its just knowing what I know now it would be hard to buy anything except an inline diesel engine. And Cummins on top of that. V configured diesel engines had been used in big rigs. But I don't see any. From what I have heard they last about half as long before needing a rebuild. In lines routinely last a million plus miles. Maybe that doesn't matter much if it never gets near those miles in its lifetime.
