That's because the X1 says to everyone: "I'm not rich enough to get a X5"
Seriously, I'm sure Switzerland is a very different market compared to USA, but there's a lot of X1 here. And although we have many more BMW models available here, the X1 is really a big hit. My seller told me it sells like hell, most of them being diesel, white, black or grey. No orange around here, and so far I saw only 3 midnight blue, including mine
