I hand my vehicles back sparkling, but I’m an old fashioned old codger and probably not typical. As long as it’s clean inside as a courtesy to people who have to get in and out of it after you drop it off, that’s as much as you need to do. The rest is down to pride in appearance, and that can be expensive if you aren’t physically able to wash and valet the car yourself and have to pay to have it done.
Enjoy your new vehicle.
