Thank you all for your thoughts, this has been super helpful.
I think both dealers are generally fine. I just know the closer one better, and feel comfortable with them. My interactions with the new dealer have been fine, and they have been pretty upfront about it all. The OTD price included all doc, reg and title fees, but not tax. That means the price differential is more substantial. The new dealer sold the used bike originally, and knows its service history, and said it has been well cared for. It did not go unnoticed by me that they did not talk down the used bike, since they know it's history and I don't, and could have told me anything.
The used dealer added some doc fees, but never represented the price they gave me as OTD, so I expected that from the start.
Any thoughts on riding experience between the B and G chassis?
