For comparison:
A month ago I bought a 2010 X5 35d w/ premium, tech, and cold wx for $34,800 and 57k miles. It also has the top BMW extended warranty. Also came with brand new tires and an additional set of aftermarket wheels w/ new tires. I too have a 2002 x5 3.0 for sale privately. The seller was of no relation to me and a 10hr drive away.
