Great dealership with an amazing guy that helped me

Great dealership with an amazing guy that helped me tremendously, Carlos Mungarrieta. I visited with him and he introduced me to a vehicle I had not looked at before. He brought it around for my convenience, and I sat in it and said I think you finally found a car I like!! I am so appreciative to him, and I am a new owner of a beautiful black Buick! A little sporty, too, I might add. I can’t say enough praises for Carlos. He worked hard on my behalf with coming down to a number that was reasonable to drive my new vehicle off the lot. Covert is fortunate to have such a fantastic employee! Thank you, Carlos!
