[NC F82]

So I've posted a couple of times about some issues with my uncle's new F02 750Li, mainly in regards to the turbo lag. He's had it since about April and has about 7,000 miles on it, and has said it is the worst car he has ever had. He is considering dumping it for a E60 550i or M5. His F02 stickered for $87K, anyone have any thoughts on how much of a hit he is going to take if he decides to trade it in. He told me to go talk to our salesmen and find out for him, but I thought I would get ya'll input first.
