I had my wife's black Lincoln Nautilus done at a shop in our area two years ago. We live in the upper Midwest, so we have the salt/ice/snow issues. They use the Xpler brand products. They had the car three days, detailed and removed all possible chips and swirls. We also had the 3M film coating put on the from including headlights and mirrors. She takes it back annually to dust it up. It has a 5 year warranty. The cost was $1450, but that was two years ago and it's smaller. From our perspective it makes a material difference. I drive a black 17 Tahoe which hasn't been done professionally but ceramic wax applied by your truly. There is no comparison between the two regarding surface retention of dirt/dust. You can take the hose and spray hers off and the dirt/grime comes right off, mine not so much.
