I have an '04 with a little over 7500 mi that has developed a minor leak in one of the rear end seals. Noticed a drop or two of oil on the garage floor and after inspecting found an area covered with a light film of oil. I'm assuming it only leaked while driving. Other half went by local dealership and part was ordered. Just something that everyone could give a quick glance. I'm sure it could've created a more serious problem left unattended.
