I sometimes need to send my cars in for work, but am learning to work on them myself. I prefer not to rely on anyone else when possible. In the future I want to have a shop at my house but don't have all the space I need for that in my current living situation. It would be great if Tesla gave people the option to order parts directly from them. I am going to go test drive one in the next few weeks. However I am going to hold off on buying a Tesla until at least 2020. Let them iron things out, see where things are at in a couple years.
