The E39 has few faults. They are bit heavy on brake pads and disks, the rear suspension top mount can break up and the upper suspension arm can wear. Listen out for a creak if you lean on the back of the car.
The pixel problem on the displays has been mentioned, as has the radiators. The rear electric windows can sieze if they are not regularly used. In the UK, we had the nickasil problems on both the sixes and the V8s, but I think most of the US sixes were iron blocks.
Air bag light can come on caused by a fault in the wiring to the seatbelt pretensioners and the passenger occupancy mat in the seat can fail (at least on RHD cars).
Nice cars, a bit low profile, especially in dark colours. For those who want a decent drive, but not be noticed.
