On the very narrow and steep alpine roads I see many Defender 90, Toyota Land Cruiser, Suzuky Jimny (or the older Samurai, "Suzukino") and still the mythical Fiat Panda 4X4 first model. When the going gets really tough the queen is the Panda 4x4. Nothing goes higher even on the snow, without chains, even on muletracks. She (the Panda is female) is usually the last, lone, parked car (car?) along an alpine road.
