Excellence service !!! I’m a repeating customer and enjoy the customer service experience. Always a pleasure doing business with you guys
I found the 2024 AT4 I wanted and I liked the Big Star price on the dealer's website as compared to other dealers. After an inquiry, Manny contacted me immediately. He responded to all of my questions via email or text for a week or so. When I finally went to the dealership, we came to terms and I left in a new loaner until the new truck was ready. It is nice to see that some dealers actually want to sell vehicles instead of trying to sell at MSRP as the pandemic pricing is long gone. T Ivey
Efficient excellent friendly caring service. Each and every one gives attention when you pull up
Great service made purchasing very easy and hassle free. Thanks for the help very happy
Wesley C was very helpful and patient with our purchase on a new 2024 Buick Enclave Avenir. It is a beautiful garnet metallic color with all the perks. Thanks Wesley for everything and thanks to the management and finance team!
Always clean, friendly and easy for me to deal with. My questions and concerns are dealt with and never pushed aside or ignored. Thank you for making my wait time easy!!
Great, positive atmosphere, highly recommend. I would refer Mr. Manny to anyone, he’s beyond great. Very informal and helps navigate you to your dram vehicle, thank God he was my salesman.
Great job by the associates who had a hand in getting the car of my liking from bumper to bumper.
Dealership was able to deliver the right vehicle with all the trimmings that I desired.
My overall purchasing experience was excellent.
My salesman was great along with the finance manager.. the pricing on the vehicle was great which is why I drove from Louisiana to purchase my truck.
Same day appointment and same day service … they fixed the problem and I haven’t had any issues past that .. thanks
Very easy to work with. They do what they say. They got me in and out faster than I thought they would. I guess the only thing negative is, I have gotten 4 surveys in the last 2 weeks about the same thing. Don't you think 1 or maybe 2 is sufficient. .
Very pleased with the dealing and service received from the Service Department. Our new truck was in for an A/C issue and Dustin, the Service Advisor, was quick to detect the problem and have a new part ordered and replaced within a few days. He kept in touch with us, keeping us informed, throughout the service and was very professional and informative the whole step of the way.
My experience with Big Star was great! I didn’t spend my whole day at the dealership. The salesman I worked with was nice, knowledgeable and professional. Would definitely recommend.
Very polite, took me as needed and work on my vehicle as soon as possible very happy with this
Everyone one was nice and very helpful. A good experience. Fernando was very knowledgeable about the truck I purchased
Very professional and extremely helpful! They were prompt and kept me updated through the whole process!
Great experience working with Adolfo Huerta. Love my new 2024 Envista!
Came from Colorado to buy a truck and the team at Big Star hit it out of the park!
Comfortable, relaxing waiting room and reliable service
Victoria was great! She had great communication, and was very chill with the whole process; she put no pressure or stress on me. Managers were great with price negotiations.
Amazing personal easy to talk to helpful friendly,amazing sales people was pretty easy and all
Good service. Able to negotiate a fair deal. Process was relatively painful. I would definitely recommend Big Star.
Dealer is prompt to answer all my questions and repair anything that needs done to my vehicle.
