I say go one further, get another car and open the door into your own car. If you're going to get dings, might as well do it under your own terms...Sort of on topic: quite a few years ago we arranged to buy our son a new car as a high school graduation present (Honda Civic). When we arrived at the dealer about 50 miles from our home we learned that the car had a tiny scratch at the bottom of one of the rocker panels.
My son was distressed that he could either take the car 'as is' or wait for them to fix it and get it in a few days.
I solved his dilemma by telling him to take it with the scratch and then he'd not have to agonize in the future when the car was dinged. I told him that the distress is with the first defect. After that it wouldn't be that big a deal for subsequent ones.
