Lexus dealerships near me (Springfield, MO)

I drove 330 miles to get to the dealership. Before I left my home in Enid Oklahoma I made sure to get confirmation on the deal. For one my wife couldn't make the trip and she has the much better credit. They said that's ok. She doesn't have to be here. She can co-sign for the loan through Docusign. Also asked them to turn the tires so the white walls on on the outside. They said no problem. Well when I got there they said she does have to be there and they didn't do what I asked them to do with the tires. They than proceed to lie through their teeth denying they said either.
