Looks good.

I agree with alexmish, aftermarket tinting is a distant second choice to factory tint. The problem is that changing them is relatively easy for the movable windows, but a lot of work for the fixed portions of the glass. I would go with an aftermarket tint, and inspect it carefully when picking it up.

I understand the European hitch option, but what did you do for trailer brakes? Are they surge brakes (automatic) or are they electrically activated, with a trailer brake controller?

It was me who raised the point about diesels not having as much engine retardation as gasoline engines for towing, but with the E70 vehicle weight and associated mechanical friction it sounds like that is not an issue. Good to hear. I don't think that using the cruise control is a test of diesel engine braking, however, as I believe that the cruise control on the E70 uses the wheel brakes for slowing down.
