Looking at another E53

[bhennrich]

I am looking at another E53 for a friend of mine as he is from Boise and I am local to the vehicle. 2006 3.0 automatic with 73,000 miles. NOT as clean as the owner said (normal I know). But it has some electrical issues I have never experienced on my X... Dome lights come on when door opens, but do not shut off when doors close. Airbag light is on but seems to be flickering. Heated seats will not activate. Pano roof sun shade retracted but would not go back forward (did not test the glass movement as I didn't want to risk it getting stuck open). Front and rear wipers were intermittently working (this was the only thing the seller informed us of before I drove an hour to see the car). Standing voltage was 11.94v, running was 14.34v. NO CODES of any kind. Idled smooth but didn't drive it as they were asking to much with all the other issues in my opinion. Any guesses as to what would cause these issues so I can try and help my friend decide how much he should offer. They are asking $6,250. But without knowing what the most likely problem is... HELP
