Purchase advice Land Cruiser or something similar stable.

Hello together, I play with the idea of buying a country cruiser or something similar and hope that someone here can give me a few tips. My current car has run 430,000 km and is not a Toyota. So I have to be friends with the idea of buying another one. Since cars are designed for impassable terrain more stable, I think that they should be very durable in normal use on the road if appropriate care and maintenance are required. also that the car is a classic car in 10 years and I can run it with my other vehicles under one number (registration in CH). So I looked at the Land Cruiser and found the model Land Cruiser 500 4.2l Diesel (year 2000). The engine has enough power, it is a diesel, it is robust and can also make experience well over 200,000 km. Basically everything fits. But for my purposes the Land Cruiser is a little too big and heavy. But on the and hen side is an E class (W211) combo also not much shorter. I would like to hear your opinion about the car. I already have a short wheelbase and a Landi is not so my world. Is there an alternative to the Land Cruiser?
