The depreciation is only valid for who is doing it, not for the owner. You can sell it at any price you wish to! That is how some classic cars get auctioned. So ask more for the old car, unless you are going crazy to get rid of it.I've never owned a car thats falling this hard this fast, bought for under 20k used 2 years ago and now it's worth only 8k with only 20k more miles. I mean jeez, new German luxury cars don't depreciate that fast, it's really soul crushing to know i've still got a long while on my note before i have literally ANY equity in this car.
