Welcome, the California is a wonderful vehicle capable to be used for a long time or high milage.
I do understand the confusion there is with owners of diesel cars and vans. In Germany courts decided that a ban of diesel vehicles in cities and towns are legal.
What that actually means on day to day basis nobody knows. Taxis, vans, trucks, buses, etc. Most of them use diesel engines for a good reason. How should they be replaced? Who will pay for this? It is easy to blame but not to easy to find a workable solution.
Diesel engines are responsible for Nx and people living in busy areas suffer, but aren't there other solutions as to ban them?
Next year we wanted to go to Germany and visit Frankfurt (I am from this area). It mighbethat we can't do this.
Never the less I would decide the same and go for the 150 HP Diesel engine. I believe that the van had the potential with this engine to see me out. Let's see what the future brings.
