Looks like a nice purchase...I agree a nice color combo...

I am trying to think what I would want to have with me on the 2600 mile drive back in an unfamiliar, but well sorted, E53 X5. What do the others think?

Do you think cooling system is original? If it were, I would probably still go for the drive home, But I would sure prefer the piece of mind of a fresh cooling system.

-check air in spare tire - and a good lug wrench
-flashlight, jumper cables
-maybe enough tools/parts to prop window up if a window regulator fails - maybe you just avoid using windows for trip.
-AAA gold membership with 200 miles of towing included.
- Maybe a list of BMW friends along the way

You might listen for road noise coming from sunroof. I have this on my '05. I have purchased the OEM E53 sunroof seal kit, just haven't installed it yet.
