Hello!
I left it blank. If you have ANY questions - do not hesitate to call VT DMV and ask the friendly customer service folks for help. They are super!
UPDATE - after dragging my feet for several months - I finally went to the WV DMV to apply for my title. The local (Martinsburg) office had never seen anything like the VT paperwork, so the lady took it and disappeared into an office with someone else for about 15 minutes.
I presume they were calling someone or looking it up online...
So she comes back and says she cannot process the title application until I get a VIN # verification...
Ah, no problem... any local LEO (Cop) can do that - so I sought out a Deputy Sheriff and had him do it. He was VERY happy to help and spent more time asking questions about the deuce than he did verifying the VIN. In fact, I had to remind him to complete the paperwork!
So my reluctance was all for nothing. This whole process was actually very EASY...
Just like finally getting fed up enough to call out the ITS a$$hole for ripping me off - and going direct to VT - I should have gone to WV DMV sooner. Nothing ventured - nothing gained!
