definately depends on what edmunds and/or cars.com as well as carfax says... if there is something on the carfax report that you are getting rid of it because of, then that won't help your cause.
since nobody else has asked yet, why are you ditching your X3? problems or just not what you want? If its problems, please share - if its something personal like want something else or $$$ than just say its not for mechanical reasons. could also be a good reason...like upgrading to a 35i or an X5 35d
