So out of curiosity I requested a trade in quote for my 2015 60kwh with Autopilot. They came back with a quote of $53,300. It was around $81k new in Feb 2015. That seems like a huge drop to me. Obviously new cars slam down as soon as you register them but 35% seems like a steep curve. Now I've noticed private party appears to be holding a much better value than that, around 10k more. Maybe that's just the luxury brand crux. Figured I'd add that tid bit for readers knowledge.
