I bought my 100D used and I don't think the original owner used those seats much and I have no use for them and want to upgrade my audio so I need the space. Looking over them I see absolutely nothing wrong with them. I had Tesla remove them for me. I believe Tesla will also install them for you. I only had to pay for 1 hr of labor since it's really just two impossible to remove bolts holding it in place. I'm In Chicago. I am willing to ship them but expect it will be kind of expensive.
