I could not find any information about expedition in Asia (mountain regions) with Mercedes vehicles. Mostly Toyotas or Defenders are needed for these purposes. Also the international organizations that work in Ostlasender (BP, UNO and s.w.) have either Toyota Land cruiser or Defender (very rarer). At the beginning of 90 the also NIsan Patruls had the (according to the drivers) were not so good. Engine weak for the mountains. Not good in snow (also in Gebirgige Pro) Toyotas (Land cruiser 100) also not very good in snow and bog. I myself have seen several times “helpless” Toiotas who have pulled oxen out of the moor. In Georgia several offroad drivers (Jaegers and Turistiche companies) are of the opinion that Mercedes landing cars are better (at least for these areas) than the other cars. Another very important thing – According to drivers Merzedes goes clearly rare Kaput after expeditions. Of course it is about large cars and not around Niva, UAZ and S.w. Someone has an idea. thank you in mainly
