The major issues on an E53 can be solved with aggressive maintenance. What you’re missing on your list is a suspension refresh. The service life of E53 suspension bushings and many of the balljoints is about 80k.

Avoid the panoramic roof.

There were about a thousand 6MT X5s built. I’ve got one and love it. I wouldn’t be in an E53 without the stick.
