I expect some stuff to be changed when anyone drives ANY of my vehicles. I'm 6foot 4. Most of the mirrors will have a great view of the headliner or sky when I drive, and the seal will be somewhere near the back bumper. I dont change the side mirrors in anyones cars, unless I cant help it, since I know how hard it is to get those back to what you liked.

I dont really know why someone would change my settings, as far as radio presets, because I dont expect to omany people to be able to find audio settings on my cd player.
