Several years ago, we were hauling a largish (14') Christmas Tree home on the roof of our Fit EV. As we were driving, could hear popping metal sounds from the roof. After we got home and took the tree off, there were about half a dozen dented spots in the roof. "Punched" up from inside the car and they popped right back and were virtually undetectable. Same thing happened the following year. I learned to use a thick pad when hauling trees to spread the load. I was never going to be able to buy the Fit EV, so not as concerned about it as a car I would actually own.
Metal, including aluminum, has a memory and will want to go back to the original shape. The paint free dent services have a very good chance of a satisfactory fix at a fraction of the cost quoted by the body shop.
