some of us speak a little bit english and so we try to answer also questions posted in english.
But sadly I personally have no available information about the ground clearance of the mentioned vehicle.
You might contact your nearest Mercedes Benz dealer or the officiel importer for your country.
If you could specify the country you live in I at least could try and supply you with some addresses that might be helpful to you.
Sorry that I can't help you any better here.
Greetings from Germany.
