Greetings! First time poster here! I have tried using the search box, but I have not found the answer to my question. Sorry in advance if I am not posting this is the right spot, but I couldn't find a better place. I am interested in trading in my car through the Tesla trade-in program and using the income toward a Tesla. I have tried checking the valuation calculator that is on the Tesla page, but it does not recognize my VIN. I think the problem is that it is set to accept only 17-digit alphanumeric VINs that became standard in 1981. I have emailed the company and had no reply. Is there a company policy that says Tesla will not accept old cars for trade-ins? My car is the 1961 Mercedes 190SL which is in good shape and is a blast to drive. But as much as I like my roadster, I think it is time to get a more reliable daily driver. Does anyone have any thoughts on this?
