Repair service

Hello dear community, I’m thinking about ordering a Model 3 soon. The service leaves, as I have noticed at Tesla to be desired! But maybe I’m just too spoiled by BMW 🙂 now to my question. Service is as good as not available, but what does it look like if I have, for example, a small sheet metal crash? (e.g. fenders pressed in, scratches in the bumper etc.) Logically that you then go to Tesla. How is the spare parts supply? Will this quickly repair or will it take forever? Thank you for your answers Greeting Andreas
