Thank you guys.

That cleared things a bit. I was anxious, as for example US version of MB GL450 is said not to have tranny oil cooling & totally different suspension,
Dealer in Europe said that Navi (on mercedes) would not work in Europe, as they are using a different system for US version.

That might be just black marketing, but got me thinking none the less.

If you compare the price:

US: MRP for a fully loaded 4,8 app. 70,000 US$ +10% duty +19% tax gives 91360 US$ plus max 5,000 shipping&insurance (of course trip expenses would have to be added) which is app. 75,000 Euro.

Compared to 72,000 for base +metallic paint + leather (not going further into configurator, appears to really make sense

Thanks again for your help guys.
