YES at 100k miles you are looking at problems! As far as electrical problems goes, I don't know what people mean by that. I have never seen a 7 series with electrical problems. I have heard years ago when the E65/66 1st came out it was referred to as a car with electrical issues (by those who never actually owned one). These cars are not the easiest to maintain especially after 100k+ miles on them. If you think you can handle it go for it but expect to pay 7k-10k on the car an within a few months an additional 3k - 5k in repairs. No one is being hard but we can almost predict your future. You will be posting what does this mean, how much do this cost etc. If you want a piece of mind look at 06- 08's. After the purchase of the 745 an the repairs within your 1st year you could have had a newer looking ride with fewer issue an that biggest thing called "A Piece Of Mind".
