I've always been a bit bothered by these searches. If you want a car you used to own, why did you sell it?
Once you sell it you have zero rights with regards to it. Buy something else and make new memories.
I don't disagree with your statement, but I can see where 'emotional' ties to vehicles happen all the time. What about finding a car your dad (or insert relative here) owned when you were a little kid and you want to surprise him after all these years now that he is on his death bed? These kinds of stories show up a few times every year. Or if due to a family emergency, divorce, (insert other reason here) you were 'forced' to sell a car, regretting it the day it happened. Then you spent the next 20 years thinking about it so you decide to go look for it now that you can afford it. I don't find any of these scenarios to be creepy at all.
I used to be indecisive. Now I'm not sure.
