Sorry in advance for what may seem like an odd post. I am thinking of giving up my beloved 2001 X5 4.4 for a 2006 4.8. My 2001 X is loaded with sport, premium, nav, shades, heated seats, and 19inch wheels, and has only 17,000 miles. What should I expect to get for the X if I sell it privately. If I trade it in at the BMW dealer on the 4.8, I know they will low ball it and then turn around and market it as a rare low mileage gem....Thanks for the input folks.
