Depreciation? Not so much but get them now
 

Tesla now going on the used-car...pre-owned market. Their offerings each come with 50,000 mile/4 year warranty, all backed up by Tesla. Many available models are the early two-wheel drive Model S 60s, leases are up and many owners have traded up for the latest AWD models. As for savings, Teslas have kept much of their values so savings are minimal.
