This time around I was impressed with the service I received from my advisor Steven Coyne and the work got done in a timely manger. The work being performed was under a mechanical breakdown claim as well as my lifetime oil contract and I had no billing issues or any issues with the work done. Thanks Chevrolet LITHIA.

Can never say enough about how glad I am that I chose to
Can never say enough about how glad I am that I chose to return to Thompson's for my second GMC purchase. The first time Bobby D. was so helpful that I requested him 2 years later when I returned. He does not pressure you. He finds out what you are interested in and why, how will you use it? He then gives you options that are available. He was able to answer all kinds of questions about how the vehicle operated etc. He is so likeable. I wish everyone who deals with the public was as polite, understanding, knowledgeable and on and on as he is. THANK YOU BOBBY! Oh Yeah, I like my 2 vehicles too!!

Van Horn is a Wow!
I dealt with Van Horn on an SUV for about a week. The vibe was so good that I ended up driving 900 miles on a Tuesday to make a purchase with them. I buy a lot of vehicles and I have never seen people stand behind their vehicles with such customer care and loyalty. They will earn your businesses.Very, very impressed and happy with their first class service and amazing warranty. I highly recommend Van Horn Chevrolet and their sales team.

3rd time buyer
I had a terrific experience dealing with Kenston now for the third time buying a vehicle. I highly recommend this dealership as they make the entire process very easy and low pressure. Matt was a terrific help to me answering questions and easing the buying process. I ended up purchasing a terrific truck, low miles and every bit as new as driving off the Ford dealership lot. Buy from Kenston, you won’t regret it.

I purposely waited a couple of months before writing this
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.

Our sales advisor, Ali, is a true professional. He provided us with a clear path to keep within our financial means. Even doing our research ahead of time online, Ali reviewed the new arrivals to make sure we did not miss any choices. Moving from the Sales Dept to the Business office, Nic explained the costs and optional packages in detail. There were no questions unanswered. Anyone looking to begin with a smooth, enjoyable sales experience with an advisor who listens, ask for Ali. We left with a car AND a smile.

If it were not for Mr.
If it were not for Mr. Orlando Tilian, I would probably be taking my car to Bremen Cadillac for service. He is the most confident thorough concerned individual I’ve ever dealt with. He should certainly be promoted to a higher level than he is currently more of the staff should be like him And Cadillac would perform better than it’s currently doing
