Original title to a 69 swinger 340 can I keep it?

If it's left blank, then fill in that you bought it for $50 - $100 so they don't tax you so much..

They have no way of telling what condition it is in, and they get plenty of money and don't need any more than you need to give them to transfer the title and give you a plate...

Good luck with that, in WV unless your name is on the notarized bill off sale, the DMV will go off the low NADA value and tax you 5%, I am pretty sure a 69 340 low value is several thousand.
Regardless of condition they want your money.
