That’s BS. I’d walk away and find another car.
I traded my pickup truck for a new Jeep on a Friday afternoon. On Monday I get a call from the dealer asking me to come in, there was a problem with the paperwork. So I go in after work and they tell me that the finance dept did not approve the loan, they need more down payment. I told them that they weren’t getting another dime from me. I gave them the Jeep key and told them to give me my truck back. I saw it on the lot, all cleaned up and detailed, I figured at least I would get a free wash out of it. After a few minutes of hemming and hawing they gave in. I kept the Jeep.
Good for you.
You were ready to walk and that brings a lot of common sense to the other side in a hurry.
