Troy,
I'm having a problem with the Owner Registry menu. On most pages there's a banner ad directly under the Owner Registry menu. If the banner ad happens to be in Flash, the menu disappears behind the banner ad when it refreshes (i.e. the animation updates). This only happens with Flash. The animated GIFs are not a problem. You can probably get around this by moving the menu to one side or the other of the menu bar to keep it away from the banner ad area.
My suggestion is to add a place to the owner registry to list any problems (e.g. differential leaks, clunks, etc.) the owner has had with the car.
