Performance Suv as X5m, Ml63 and etc, are the best suited cars for countries with cold climate. we have cold winters (-20c) with a lot of snow, and we still want to buy 4wd high car like suv, but still want it to go fast, that why they are so popular in Russia and Kazakhstan. British people (top gear) saying that they are completly pointless, maybe for small and warm country like Britain. But for us they are obvious choice if u have money to afford them. Diesle will just freeze in this kinf of climate. And cars like m5 and etc, are real wheel drive, so no use at winter time. 911 r8 have all wheel drive but there are to low, so it wont be possible to park them in our countries cause we have pretty high road ''borders''
