We went there to drive test three used cars. The first couple ones had issues, but we liked the third one. a 2004 highlander with a 7500 $ price tag. we put an offer to take the car and pay it upfront. So, we gave an offer that is 2500 $ less. The salesperson was very nice and very professional. He took us back to the office, but he could not give us a response without his boss's input (the general manager) ... after he brought us the deal which included all fees and taxes, we told him that we made an offer he went back to his boss and then they both came back.
The general Manager ranted at me and my wife. He was almost yelling at us. After he stated his perspective of the deal, He mentioned that we spent 2 hours with his sales person, that our offer was not fair, and that we do not deserve that car.
The general manager was rude and unprofessional after all, he failed to negotiate our offer because he never gave us an alternative one.
Mr General manager, you had two serious buyers who were willing to buy upfront and negotiate a fair price for both of us, but you have failed to manage the situation. Instead, you got offended, you lost your temper, and you failed to make a deal or leave a lasting positive feeling about Mazda Evanston. Please, let your salesperson handle it.
