Cadillac XT5 – license plate mounting on the tailgate –> drilling into the sheet metal indispensable?

Hello colleagues, I am interested in a Cadillac XT5 as a new car/day registration. I have now studied various new car offers on the Internet. Among them offers with photos of vehicles still without registration plates. I noticed that there seems to be no prefabricated holes/threads in the tailgate, which could be used later for fixing the license plate or a license plate holder.Did I recognize this so correctly? Are there XT5 owners who confirm this o If it’s like I think I’ve seen it, then it’s almost a “no go” for me to get the XT5. Missing holes in a tailgate made of sheet metal mean that you usually have to bore into the sheet metal. Ergo makes me (unnecessarily) a source of corrosion. In the case of new cars, which stand at the dealer, it’s often the case that the holes are already drilled and empty plate holders are mounted. I myself did it years ago with a new car. Car collection was experienced, where I had claimed a wrongly seated plate holder and then where before my eyes was drilled again quickly into the sheet metal, so that the plate holder could be mounted straight. I could not look at it at all so quickly. When I left the car after 2 years, I dared to look under the plate plate: rust base. Sure. The holes were also not protected in any way against corrosion. all. Alternative would still be to attach the plates with Velcro tape. For this there are probably corresponding solutions, which I have seen at Amazon. But this could prove to be a problem, that the Velcro tape does not have full contact with the tailgate at the back, because about where the plate should go, is a small depression in the sheet metal.
