I am currently a 330ci owner and looking for a X5 which I always wanted. I found one but not sure if the price is right. Checked KBB but still want to know what you think

Its 2003 3.0 with 43K miles
One owner, all records
Grey with Black interior
All options:
Navigation, sport seats/steering wheel/leveling suspension/parking sensors/heated seats/xenons
The guy wants 26900 for it.

Is this a good price? How much should I offer.

I can pay his asking price but I dont want to owerpay....
Thanks.
