Dealer won’t budge even with the recent auction data.
Maybe negotiate a grear deal on a comparable car (ie Ferrari) and then show the Aston Martin dealer where you are and see if they will match it?
The dealer is buried and waiting for a sucker to pay an absordant amount above real market value.
That sucks. But happens often. Gotta wonder just how buried they truly are. My reply to dealers like that is “you made the mistake, and I’m not going to be the one to bail you out. Good luck.”
