Last winter I asked Tesla for a price as a trade in on the Y just for an idea of how little they would give me as I had a previous experience and was not expecting much at all. Turns out I have FSD which they give you 0 for and also AB which is worth 0. Bottom line is the car was a hair over 3 years old, paid around 85,000 cad and they offered me 25,000. Going rates were around 45,000-50 every where I looked without FSD or AB. When Juniper comes out either I will sell it locally or hang on to it for a family member.
When I bought the MS I asked to trade in my Mercedes 43 AMG which I had paid 90,000, they offered $25,000. Sold it privately for 53,000.
Maybe this is only in Canada but I would call it lowball on lowball. The Merc was a company car so I bought it for what they offered me as proof of value, made 28,000 when I sold it a year later.
