Xdrive ja oder nein?

If you need Allrad, then yes.

I’ve got a little one and with dry driving, I’ve got no problem with traction. In case of a wet road, I’ll drive adjusted anyway. If we have snow, I’ll go anywhere.

Depending on the area, it makes sense.

Otherwise you have at least as much disadvantages as advantages. More weight, more consumption, more power loss and need to pay more attention because the distributor gear reacts toxicly to many changes in the chassis, the track and the rolling circumferences.
