Service department and staff rocked!
Service department and staff rocked! Anthony and Gary were great! Ruben was so nice and friendly also! Those guys were easy going and made me and my kids feel welcomed!
So much better than prior GMC Yukon
I came to this car from a 2016 Yukon which was a rolling dumpster fire. At 102k miles, I haven’t had a single failure with this car. It tows extremely well, the seat comfort is by far the best I’ve ever owned, I don’t love the exterior styling, but its such a great owner experience that it doesn’t matter. Maintenance is like owning a Camry, cheap and infrequent. AWD system makes driving in all conditions a breeze. Great vehicle.

SIGN ON GATELIFT COVER.
QX 80 is very comfortable driving. Despite it's size, maintenance is great. Thieves often mistaken the rear gatelift cover to be something valuable hidden inside thereby forcing it open and causing damage. May be a sign may be necessary. The current look is nice but attractive to thieves who have no idea of what it is.

Everyone was very helpful and kind.
Everyone was very helpful and kind. I requested scratch repairs on my purchase and it was completely taken care of as discussed. Salesman was very nice and no pressure!
Luxurious beauty.
Most sturdy, luxurious and roomy car I have owned. I feel safe when driving this car, it is a very smooth ride and a noticeable eye catcher, boy am I blessed.I love the body style. The only kick back is the 3rd row leg room is a-little to short, my family have long legs, as long as they don't ride back there its wonderful.

Sales customer service was the best experience ever !
Sales customer service was the best experience ever ! Candace could not have been nicer, more accommodating and made the process painless. Alex facilitated the transaction and the same. we are very happy and would continue to buy from her and Alex! You can buy a car anyplace, why not where they take great care of you instead of the stress normally associated with buying a car. 10 stars....

This dealership does a great job of offering a wide range
This dealership does a great job of offering a wide range of used electric vehicles at some of the lowest prices in the Valley. I worked mostly with Angel (and a bit with Eric). Over the course of a few weeks, we narrowed in on the EV that was right for me and that qualified for the $4,000 EV tax credit (which ends September 30, 2025). Both Angel and Eric were personable, professional, and responsive. Ultimately, I found a great car at a great price here, without the haggle of negotiating. Please take care to read through all the fees and warranty offerings. You want to make sure you are purchasing what's right for you. But, I did find the fees + taxes to be outlined in a transparent manner. I'll update this review if I start to have any issues with the car in the immediate future, but so far, this has been a good purchase.

I found a 2016 Ford flex online through true car and set
I found a 2016 Ford flex online through true car and set up an appointment for a test drive. Greg Morris was quick to respond and kept in touch with me answering all questions up to my appointment. When I arrived the car was out front. I had to wait a few minutes but not long and we went for a little test drive. I had already been pre approved by my bank for the loan so I went to get the check and Greg had my new car washed for me and waiting by the front Door. Signed all the paperwork there is a bit. Total time from appointment to complete was 4 hrs. But half that I was at the bank because I filled out my paperwork wrong. Had I done it correctly the dealership would have been able to complete that portion for me and save time. This dealership is full of gorgeous new jeeps and chargers and lots more. I had a very nice experience thanks to Greg! I absolutely love my new to me car!

I had an excellent experience at Kelley Buick GMC.
I had an excellent experience at Kelley Buick GMC. From start to finish, the team treated me with professionalism, honesty, and respect. They took the time to answer all my questions, walked me through every detail without pressure, and made sure I got exactly what I was looking for. A special thanks to Gustavo Sanchez and Russell Hernandez — both went above and beyond to make sure the entire process was smooth and stress-free. They were knowledgeable, patient, and genuinely cared about finding the best fit for me. The finance process was straightforward, the dealership was clean and welcoming, and I never once felt rushed or “sold.” If you’re looking for a dealership that values customer service and treats you right, Kelley Buick GMC is the place to go. I’ll definitely be back for my next vehicle.
