Ashley is top notch with knowledge and service and patience! Everyone at the dealership is helpful and accommodating. Thanks for everything, Ashley!

Nice styling,interior has a new design dash which is beautiful and convenient,safety features and cameras are great and easy to used and the active cruise is awesome.

The response time was really fast, I had received an email back within an hour. I was actually surprised how quick they had contacted me about my inquiry and I would recommend them to a friend

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!

We've had only the best service with Diamond Hills. Everyone we have come in contact with over the last 2 years has been pleasant, courteous and helpful.

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

Aaron has been very courteous and professional during my contact with the dealership. He's gone above and beyond in his approach to customer service.

We drove two states over to McKenzie Buick GMC in Milton, FL to meet with Nick and make a purchase on our new Yukon Denali. Customer service was top notch. We were going for their 2019 Yukon Denali to replace a 2008 Tahoe LTZ. We are very pleased with the vehicle. The upgrades are wonderful. Love the cooling seats, the wifi, the HUD and even days after our purchase they have reached out to check on how we were and mailed us a small gift that meant so much. We will definitely use them again if they ever have what we’re looking for on a future purchase. - Brandon Howell 2019 Yukon Denali

True to word, respectful to customers and their time. very happy with the purchase, without trying to sell me other stuffs. thank you for pleasant and easy transaction.

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.

Bought truck remotely. Rigo the sales manager assisted with the purchase. Car showed up later that day and I couldn’t be happier. Followed up the next day to make sure i was all connected. Will recommend this dealership to everyone

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.

Overall I am very happy with my new Truck. GMC however needs to address their software glitch where the display screen intermittently stops working or the audio cuts in and out. I keep hearing a software update is being worked on but that was a while ago?

i greatly appreciate diamond auto for helping me buy my car ,they were very very helpful with the process ,i will defiantly return in the future

I bought this 2017 Tahoe w LT trim new. Have 60K on it now and have had no issues with it. We are not towing with it or doing high speed racing so we find the 5.3L Motor is smooth and quiet (and have not had any lifter issues which others have reported). Transmission and suspension also smooth. We keep Michelins on all our vehicles and have found this Tahoe very quiet and comfortable for road trips with 4-6 people and luggage. The LT trim pkg deleted some comfort items I wish I had (like heated steering wheel) but it still is pretty much leather-and-loaded so it was a good value at the time. I have had Suburbans for 35yrs before purchasing this Tahoe and I will probably go back to a Suburban for the extra cargo space when I trade this Tahoe in. But this has been a nice and reliable vehicle for us. No complaints.

Thank you DCH for making it so. Nick, the affable and knowledgeable sales person, guided me through the low pressure decision. As I waited in the sales room during the process, I could hear the other deals being discussed in a personable manner from a team confident in their product and caring for their customer. This is the experience you want for your friends and family. I recommend Nick and DCH Honda to anyone looking for a great car and a friendly helpful team.

I love my Acadia Denali. It is fully loaded with anything you can think of.I love the V6 engine and how smooth it drives and rides

Dylan was amazing! The experience was easy and relaxing. I felt Dylan listened to my needs and never felt any pressure. He was professional and kind.

I have had this car 5 years 90000 km. No problems so far, it has been exceptionally good. The only money I have spent is gas and oil changes. I. Would buy another one

Our AT4X has been an excellent mid-size truck. The ride is shockingly smooth and the engine has a lot of torque. Wish the interior had less plastic and GM's failure to have a rear view camera mirror or controls for garage/gate contols is inexcusible. Overall, could not be more pleased with this truck.

Good overall experience. As always, the dealership tried to slip in extra fees. This does not make this dealership any worse than others, but I won't give 5 stars when this happens. In our case, the sticker price was not what we saw when we sat down to negotiate. There was a $1,300 charge added for a security feature the dealership had installed. I had that removed: sticker price on a used car should be everything that the car is. I did not choose a $1300 option. The dealership worked with us and was friendly, except for the finance guy. It was late at night and he got a little snippy.

I have loved and owned Chevy and GMC midsized trucks since 98 when I purchased a used S-10. My latest purchase is a 2021 GMC Canyon Denali bought brand new. It's been a great truck until my power steering unit went out due to corrosion. It only has 32,200 miles on it and I have never gotten it wet other than car washes and driving in the rain which is normal conditions. I had purchased a mid grade extended warranty through GMC after my lease was up and purchased the truck. I am being told this is NOT covered due to it being external wiring. So I feel this is a manufacturing malfunction and bad engineering for water to be able to get in to cause such corrosion so beware. This is an open case filed with GM currently to hopefully rectify the matter.

Dealership a little slow on responding to a meeting although the personnel were very personable when we met. I just wish they had pointed out that the car did not have adaptive cruise control or heads up display which evidently came with the upgraded version.

Great customer service and very friendly! All repairs done perfectly and my Chevy is still brand new! Highly recommend and I will be coming back for sure!

I ordered a 2022 3500 SRW Pro LB Double cab 4x4 in silver metallic / blk cloth. Added preferred package; gooseneck pkg; X31; upgraded wheels; camper/Snowplow prep; black steps. Got the 6.6 gas L8T. No start/stop and runs on all 8 cylinders all the time. I Love this truck. Had Rams and Fords in past. This is my first GM truck. I am in my 50s so not a brand thing... just a great truck. It was delivered in June. Truck rides great, tows very well, reciever or gooseneck. Fuel mileage is outstanding! Especially for a 4x4 one ton. I get 16 to 18 highway when not towing. I was shocked by how well it did and impressed with towing mpg as well. I generally tow between 6 and 14,000 lbs. Loads include a Glacier bay catmaran boat, 30' camper, and 3 axle 25' gooseneck. Truck easily handles those loads. The L8T engine is smooth and powerful. The 6L90 Transmission functions perfectly. If something were to happen to this truck I would not hesitate to order an exact replacement. So far very satisfied. MSRP as ordered was $53,945.

They did absolutely wonderful job. Knowledgeable and professional. Salesman was extremely helpful and very knowledgeable and they did not pressure us into anything. Thank you.

Had my 2024 Canyon for exactly one year. Not a single real issue once over the air update was done and that only affected the radio. It was an AT4 in desert sand metallic. I traded it for a 2025 Acadia, as I missed life in an SUV. However if you want a truck, I’d highly recommend it and specifically the AT4 model. It’s got meaty tires for pothole protection, it’s able to tow more than you can imagine, it looks super amazing and you’ll have lots of thumbs up and positive comments when you get gas, etc. updated tech was more than you could ask for. 4WD auto mode worked flawlessly. Engine had a nice little growl that I miss too. Let me say if you are a truck person or want to be a truck person, it’s a perfect mid size truck. Mine was 100% and am missing it yes but love the Acadia because it’s also a great vehicle. Got the AT4 Acadia and for my situation it’s perfect.

One very awesome vehicle. Checks all the boxes you need in a truck and exceeds expectations on quality, performance, and looks great ,too. Love my nre truck.

Great service, Alex H always delivers great customer service . Communicates progress on my vehicle . Alex remembers details about my family which is genuine and hard to find. She’s my go to .

I love my new Hummer, I have had it 2 weeks now and it’s an Amazing vehicle. Looks great and is a lot of fun to drive. I love that I can take the 4 tops off and it’s a convertible suv. So far so good with no problems. It charges overnight and is ready to go. I would highly recommend.

Although the car we wanted didnt work out, the customer service was excellent. MARCUS is a STAR! He should be in management. I have brought many mercedes in the past. Carmax is turning the tide when it comes to purchasing vehicles. The best thing to do when you buy any car is to take it to another mechanic, and then bring it back to the place to be fixed within the warranty period. The Truck I purchased from them a year ago had a few issues but they did take care of it and I've not have any problems since. Carmax has set the bar high for purchasing returning and anything to do with cars. BRAVO!

We purchased the Denali Terrain 2023. The car is great. I have had four knee surgeries and needed a car to get in and out easily and comfort seating. The controls for adjusting the seat just the way you like are great. I am troubled also by back problems and totally love the heated seat when needed. Sometimes I just want to ride around and turn the heat on and adjust seat so my back feels better. The different controls and are numerous. I love the safety control warnings and info with traffic. The screen is fabulous and helps so much. When ever I park I like to drive in and park and then hold on brake put it in reverse so the screen then comes on and shows how I parked. I like the levers in cargo area for putting seats down and also like how flat they sit. Plenty of room. The back seat is roomy even when person in front is back. Enjoy being up higher than a vehicle. I feel I can see more and it also makes me feel safer. The Terrain looks beautiful and love all the chrome in front. The car seems bumpy but not as bad as our last. The roads are in rough shape here. It has a lot of pick-up my husband demonstrated that to me and he wont be doing that again unless it is necessary. It is a turbo 4 cylinder and can not believe the power you feel. All in all Iove the car and getting good mileage. Purchased car from Boucher in Waukesha. They were not pushy. Explained everything in detail and were very fair. Great place to purchase!

Excellent overall experience. Sales representative was not the most knowledgeable, but was very attentive. The facility was clean and sales did not apply pressure. Representative made several follow-up calls which were appropriate and helpful to my search.

We are very happy with our Terrain Denali. Our first choice was the 2023 Lincoln Corsair 1a but there are no in inventory. The Terrain Denali was 1b. Great styling exterior and interior

Thank you Carlos Gonzalez and staff for working with us and providing us with extraordinary customer service. We’re very happy with our new GMC Sierra. My husband and I had been looking for a truck for months . Thank you for working with us.

As we age, our reaction time may become slower. This vehicle is loaded with features that make me a safer driver. It connects wirelessly with my iPhone for hands-free Apple CarPlay. Love that! And the Acadia is a dream to drive. It’s the perfect size for me and my family
