    I purchased my car from Eliot. He was very knowledgable and made me feel comfortable about my purchase. He knew everything there was to know about the GMC. Bill in financing worked to get me the best APR possible. I would definitely use this dealership again in the future!

Shelly Barr did a fabulous job getting me into the right vehicle. Made me very comfortable with the dealership and introduced me to a number of staff. The entire time was great.
