It took a a year to get my Model X into an "acceptable" state, and it still has seven outstanding issues, six of which they simply refuse to fix.
If I wanted to get another service appointment now I would have to wait at least a month, and if they decide they're actually going to try to fix something (they often refuse), they keep it for at least a week and no, you don't get a loaner car in return.
It is an absolute disaster and I would recommend no-one ever buy a Tesla simply for this reason.
