When I was hit by a drunk driver in my DeLorean, the insurance company gave me the option of buying the car back at something like $5,000. When I declined and the car went to auction, it only brought about $2,000 (this was almost 15 years ago). So it's still possible to get your car back if you change your mind, and possibly at a much lower amount.
That being said, don't let all of the well-meaning peer pressure on here add to your stress. You don't have to justify your decision, either. Do what's right for you & your family. Should you want to buy again down the line, there will always be other DeLoreans for sale, and the community supports you regardless. Best of luck!
