+1 on the nice E53 smell. When I bought it, it sat right next to an X3 that smelled terrible. It enhanced the perception that the X5 was in a lot better condition, even with 84K miles, so it got bought. BTW, I was originally shopping Jeep Liberties, which all smelled terrible. The X was a couple years older with a few more miles for about the same $$, so...here I am, an E53 owner.
