Although I don't and won't…
Although I don't and won't ever own a Cyber truck, I have owned 2 Model 3's and currently a 2024 Model Y. My first M3 was mid-range which was less than useless in Chicago winters for range and traction. I already had an electric smart with a range of 80 miles, and it's rear wheel drive far bettered the traction from the M3, but I digress. I tried selling the M3 back to Tesla in 2018 b/c I wanted a dual motor version and despite the car having less than 5,000 miles on it and being 6mos old they said they would give $12,000. I sold it to Carvana for $38,000 a week later then paid cash (again) for another M3 but this was a Performance version with Full Self Drive. I drove that one a little over 4 years, put just under 38,000 miles on it driving between Chicago and LA twice, and would kept it but the "one time" offer to roll my FSD into a new Tesla got me to buy ( cash again) a long range dual motor with power boost 7 passenger MY. This time they offered $16,000. I sold it for $26,000 to Mercedes Dealer.
Bottom line, even IF they say they will buy back, they offer pennies. Don't bother kidding yourself, they are in the call SELLING business, not car re-reselling business.
