I would recommend Carheroes to anyone. The whole experience with them was great. They worked quickly and smoothly to get the deal done without any hassle. Thanks to Rob, Zach, and Patrick!

I love it the look the interior mine is a red one and it looks so good and it’s my baby and it runs so good and the technology is off the chain

Sebastian at Car Heroes has been amazing to work with. I have needed to shop remotely since I am relocating and he has been nothing short of exceptional to deal with. Thank you!

Needs new monitor. brakes look great to me. No noises. dealer says parts on order GM strike. Can't replace myself cause of computer...

Bruno is an amazing service advisor. The attention and care that crown provides is by far one of the best in the industry. I would definitely recommend this dealership for service.

Stong engine and smooth! Highly recommend for familys or someone who likes a smooth truck. Purchased new and have had zero issues since then. Love it!

Dylan was amazing and was really helpful showing the car I want. Lot of good Camry out here. Got me a really good deal! Thanks Dylan

Looked at more expensive truck with less options, bought the GMC SIERRA AT4 Turbo Diesel 6. I now only put fuel im once a month. And long distance trips are easier due to better fuel economy. One of my best investments ever.

Great experience. They were professional and treat their customers with respect. I would go back there when I need another car.

I needed a new pickup and while I wanted a Ford F150 I could not find one set up how I wanted. When I did the Ford dealers didn't want to give what I felt my trade in was worth. I got what I wanted and got a great deal on a 2024 GMC Sierra 1500 Elevation. It is even set up better than the F150's I was looking for and at a better price. I'm very happy with my purchase.

Highly recommend Rivard GMC Buick. Haley was our sales consultant, and provided a no pressure, no games sales experience. Straight forward pricing, without all the money making add ons. Family owned business as well.

Got the duramax diesel and getting 24 city and 32 highway is very good. Truck drives nice and is very comfortable. My 2 issues with this truck is the backup camera at night is useless (very dark) and interior lighting is not very good. You would have thought a 78k truck would have footwell lights, but it doesn’t.

I worked with Jake Thompson and if there was any heavy lifting to do during the sales process, he did it. It was no doubt the easiest purchase of a car that I have ever made. Thanks Jake!

I have a 2023 GMC Sierra 1500 Denali with the 3.0 Diesel engine. I have 20,000 miles on it at the time of writing this. Never owned a diesel before and now i don't think i will own another one without it. I LOVE the engine in this truck. Only complaint would be that it likes DEF fluid while towing so pick up some extra DEF before you head out to tow something. Put about 8K miles on it this summer without adding any DEF fluid. seems to use a little more in the winter or when towing. Very quiet for a deisel and the fuel economy is awesome. Driving 70 mph down the freeway this truck gets about 30mpg, Drive 55mph on regular highways and this truck gets almost 40mpg. All around driving for me is about 26mpg. I used to fill up twice a week with my gas motor and now only once a week. Wireless Apple Carplay works great and the voice texting and mapping is a big plus. I also have the new SuperCruise feature which is awesome. Get on the freeway and set the supercruise on and the truck drives itself until i get to my exit (about 28 miles from home to work). Bose stereo is out of this world and all the storage is great to. I have a swingout bed toolbox, aluminum roll up tonneau cover, Lighted black GMC front emblem, Gloss Black 22" wheels, All Black decals and my dual exhaust bezels are black as well. I rotate the tires and change the oil every 5,000 miles. Couldn't ask for a better truck. Might get the ultimate next time as that has the messaging seats which i kinda wish I had.

I has my NX250 serviced today. My advisor was Jose. Prior to having my car serviced he explained everything to me and stated that it would take approximately an hour and a half. I also had a question about my audio system and he was able to answer it right away. My car was returned to me faster than Jose had started washed and ready to go. Jose was fantastic and I would highly recommend this dealership for all your needs.

My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

My latest service experience was once again a very pleasant one! Service writer Mark went above and beyond!

This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

My boyfriend bought his car from Carmax and it was a great experience. So when I needed a new car I looked at Carmax as well. They had everything I wanted but I thought I would get a better deal at a dealership... Boy was I wrong. Went to three different dealerships almost went through with a deal but they couldn't get me a good interest rate. It was so painful and awful I had decided to give up and just sink money into my current car and try again next year. I had an appointment at carmax the following Sunday and Dwyane called me to verify the time. I told him what happened the previous day and said I would be keeping my car because I needed a good rate and didn't want to be making crazy payments. He said, I hear you and totally understand, I'm happy to help you whenever you're ready. Just so you know when you are ready I have a good rate for you so I know we can find you something to make you happy. I was surprised because the other dealership said we couldn't get close to what I needed. Well folks, I'm in a new car, my payments aren't crazy and I have peace of mind. We are Carmax people from now on. Thanks Dwayne in Clearwater!

I've only had this truck for a month and a half and have had no issues. The interior is just plain awesome. I really like the multi function tailgate on this truck, it's very handy loading stuff into the box and the step really helps when you want to climb into the bed. I really like the ride height on the new trucks better than the 2015 Denali I traded in to get this one.

Buying our vehicle at Kelley Buick GMC was a great experience. Our Sales Consultant Braxton Nyland was waiting for us with the vehicle ready to test drive. We loved the vehicle and proceeded to the showroom to work out the details. To our surprise everything was up front and open, no exhausting back and forth. The General Sales Manager Brandon Wundrow also checked to make sure we had everything we needed and thanked us for our business! In no time our new vehicle was ready to drive off the lot!

My 2022 GMC Sierra 3.0 Duramax pickup truck is a good truck. I work on a farm and I also drive an hour to see my girlfriend. For the farm, it has excellent towing capability and for the hour long drive to go see my girlfriend, depending on the weather for traveling, I can get up to 35 miles to the gallon!

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.

I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!
