S.H.
you are in a pickle....since you don't hold a lien-free title to the car. As others have mentioned, buyers only have 30 days to license the car....& it'll take that long or longer to get the title back from the state.
Honestly, bluebook the van....be informed as to its value & then take it to a small-lot dealer & see if they're interested.
Hard to make a sale without that clear title!
EDIT: now that I think of it, we immediately skip over used cars without clear titles when we're buying. Sorry!
