I'll be going to look at one about 2 hours away next weekend. From the photos it looks good. Only has 127,000 miles.
I'm also going to borescope that cylinder and see if it looks like its valve or rings. If rings, I'll try a ring soak and see if I can get the compression back up close to the rest. I hate to get rid of it. I've had it so long and it's been a great car, still is.

Having just done two engine swaps, i suggest looking into rebuilding or finding a rebuilt or young m54. My x5 is the next gen 2011 and it was 1/3 the price to replace the motor with 80,000 mile newer one than replace the car.
The e53/m54 would easily be half the effort of e70 n55 swap.
