Alabama. Visited a motorcycle dealership interested in a 2015 bike. Met with Sales for 5 minutes they collected my information and because I knew what I wanted handed me off to F&I. The F&I guy took my deposit and told him I'd be back in a few days to finish, pay the rest and pick up the bike. I came in a day early without calling my plans changed just to finish the paperwork would still be picking up the bike the next day. I worked with a different F&I person who completed the paperwork, collected the balance of what was owed and provided me a signed bill of sale. Now the dealer calls me to inform me that the wrong bike was listed (2016 not 2015). Admittedly I didn't verify the bill of sale prior to signing it-just assumed it was right (my fault I guess?). Anyway the dealership wants me to come back in to resign a corrected bill of sale. What are my options? Do I have to resign?
