How screwed am I?

Just hope they didn't apply for a lost title (which would void yours) and junk it so they didn't have to keep paying taxes on the car. I had to do that with 2 cars I sold, the new owner never transferred the title and I was required to pay the taxes the next year even tho I sold the car... So I applied for a lost title, took it in and junked it... Never again will I sell a car without meeting the buyer AT the DMV and transferring the title immediately
Glad Illinois don't work that way.......
