This post is a little old and after the fact now. Just adding info.
From my experience (not just reading about it):
In my state (other states are different, especially GA), a vehicle that hasn't had the registration renewed in a long time is a "red flag" with the DMV computer system regardless of the title, VIN tag and engine serial number. In this case, proof of ownership and vehicle inspection MAY be required. Sometimes our NCHP does the inspection. The logic is to catch stolen classic vehicles. My state license plate agency can provide a printout of the DMV records of previous owners and their addresses up to (? have to look it up) years back. Title transfer would require signature of the last owner, or legal heir (with paperwork), and buyer witnessed by a certified notary or certified plate agency notary. The owner-seller and buyer do not have to meet. Their signatures has to be witnessed/notarized.
Any auctioneer who deals with automobiles would know this.
I THINK (I don't know) in most states it is illegal to sell or auction a vehicle without a valid (provable) title.
Without a good title, you are basically buying parts.
