Excellent service from start to finish. A pain free process. Easiest car transaction I have had buying a car to date. Gunn is excellent, as always.

Shoutout to Jesse Gomez! He worked around the clock to complete an extensive list of repairs on my beautiful vehicle. I’m beyond grateful for his dedication and attention to detail. Thank you for the excellent customer service — what a clean, fine establishment! Highly recommended!

All services on my vehicles have been performed by Gunn GMC. Customer service is an area that I expect as a customer to be top priority. Hope they can turn around and provide better customer service and a clear understanding of the service process and wait time. A lot of wasted time can be saved to all parties if they just simply communicate properly upfront with all customers regardless of the service needed and communicate properly of the overall health of vehicles. Receiving service recommendations from the local Firestone after servicing my vehicle by Gunn GMC really makes me question their multipoint inspection, report of findings and service recommendations.

Great customer service my service advisor did an excellent job from time I got there to the time I left.

Went beyond to check the issues with my vehicle. Pleasant and professional. Thank you for everything

DealerRater Mar 28, 2025

The service was great! Was having issues with my Sierra starting. Turns out it was a bad battery. So they replaced the battery and while my truck was there I had them change the oil. They had me fixed up and on the road in a short time.

DealerRater Mar 11, 2025

Prompt service, good communication and exceeded expectations. Very polite and made sure everything was taken care of.

Great experience! This was the easiest car buying experience we have ever had, no games, no haggling. Would definitely recommend Gunn for your car buying needs

DealerRater Nov 12, 2024

I have purchased probably 15 vehicles from Gunn over the years always had a good experience.

I'm a consumer and was at the dealership looking at a truck on July 23rd with Braden(Nice kid). He went to get Piotr Zelaskowski when inquired about paying out of my TRUST account. Piotr said yes. Then asked how. I said I'd write a check out of the TRUST. He then flew off the handle claiming I'm trying something I seen on tiktok. I told him I don't have tiktok and I'm being serious. He refused my business. I offered to show him the UCC codes and USC codes which all business and corporation's must follow and would validate what I'm saying. He agreed, then as I opened my book to show him he told me to leave the property. I've never been treated so rude and disrespectfully like this by a representative of any company in my life. I emailed the General Manager about this and he never responded. This site won't let me rate 0 stars, that's what they deserve. I'm filling complaints with BBB, Consumer reports and the DMV.

It always very clean. Most of the time greated quickly, not this time. Maybe because Jesica Lopez is not longer working for the dealership.
