The paperwork I got from Tesla not long after confirming my order says that they will take trade-ins "...through our multiple partners, including AutoNation." I am going to email my DS to see who the other firms are, but she is slow to respond. Does anyone know if I can trade though CarMax? For my Ford Fusion Hybrid, AutoNation quoted me (online) $17,500. In person, here in Tucson, CarMax will pay me $19,000.
