My stock door sills were cracked when I bought my car from the previous owner. I contemplated spending the $1400 for the Tesla Carbon Fiber Door Sills, or buying these from eBay Carbon Fiber Door Sills for Roadster. Instead, I decided to buy this Carbon Fiber Vinyl Wrap made by 3M on Amazon. It took about one hour and I only had enough Vinyl to cover one sill, but I was very impressed and will be doing the passender sill in a week or so when the other roll comes in. There are a few imperfections, but overall I think it looks really good. I'll provide an update when I find out if they show scuffs and how easy they are to clean.
