Senior management of the dealership group apparently learned these lessons.
Lower level guys react out of fear, play CYA and so shame the entire organization.
It's like a Greek tragedy the way this gets played out again and again in organizations.
However, people on here who say 'a contract's a contract's a contract's a contract' need to spend some time with the ALI Restatement of Contracts, and some case law.
If party A makes a mistake in the written contract, like in price, and party B knows it or has reason to believe it, then party B can't sign the contract and take advantage of it.
That's generally the law, and that's ethical.
