I had something related happen a few years ago at a BMW dealership. When I made them an offer (which honestly was not even anything LH Hall of Fame material, just a good solid LH type offer) I told them if they could do this deal I would come down and get two of them that afternoon.
Their reply——
“Kindly sir, we do not want to sell you one car at that price, and certainly not 2. Please have a good day”
I’m almost certain they blackballed my name and number
