Cheyenne did an excellent job. She is very knowledgeable and her feedback helped me to make the best decision at the time of purchasing the vehicle. I highly recommend Cheyenne to be your sales person.

Fast friendly, got the deal I wanted. Followed up the next day with a car wash and I was on my way. I plan on using the maintenance department for oil changes in the future.

I purposely waited a couple of months before writing this review because I wanted to see what kind of follow up Rainbow did and I wanted to go through the first service of the truck with their service department. I purchased the Sierra 1500 truck with the small diesel engine in April. It has been a fantastic truck so far and I am getting over 30 mpg on the Causeway. First, it was a pleasure dealing with the salesperson, Rocky Comeaux. She was not pushy, she listened and she answered questions. There were two questions that she did not know the answer to - and instead of making up a response, she asked someone in her department. Having been in sales at one time for 8 years, this was refreshing that a salesperson did not try to "look good" in front of the customer and not look like she did not know what she was doing and made sure my questions were answered correctly. Rocky has followed up with me several times since the purchase to make sure that I was satisfied with my purchase. Second, I traded in a 2004 Dodge Ram truck with over 360,000 miles with the original motor and transmission. I take care of my vehicles, and longevity of the truck was important to me. As such, the long term warranty options were of interest. Rainbow explained them, and they treated me fair on my trade in. Third, paying for the vehicle was easy and picking it up was seamless. Fourth, I recently brought the truck in for the first oil change and service. The service department was booked for over a week but getting the appointment was easy on the app and I picked up the truck later that day at my convenience. The only hiccup on the service was that the DEF was not refilled. When I brought this to the service department's attention, they immediately apologized and filled it up asap. The service department was very easy to deal with and very friendly. I would highly recommend this dealership. This is my second vehicle I have purchased from them as we have a 2013 GMC Suburban still going strong.
