Dealer installed options can be problematic, My dad's last car had some dealer installed trim applied to the door sils, they drilled holes to mount the trim, and didn't properly re-seal the metal, so it rusted. Dealer installed radio in a previous car had faulty wiring. Friend had a car where the dealer had replaced the normal badge with the premium hood ornament. Rust again.
