I inquired about a Camaro Convertible that had just arrived, Pablo replied and actually sug the car our if the snow and did a complete video walk around. Since I live 400 miles.away and this was exactly the car my wife wanted I was excited to have Pablo helping me. I asked him to look into the price and I had one more to call on. I called back the next morning got the price, made an offer. Unfortunately we where to far apart and the other car sold. My bad luck.
Like the truck but also disappointed
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.

Austin Ellenberg helped us find the exact Buick Enclave
Austin Ellenberg helped us find the exact Buick Enclave that we wanted. He was very nice to work with and patiently helped us understand all the new features on the 2025 car. His explanations of everything were excellent, and we appreciate his offer to talk with us again about any new questions that we come up with. We also appreciate that he had a new battery installed before we took possession of the car, since the previous extreme cold temperatures had run down the battery while the car was on the lot.

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!
2019 Sierra SLT X31
I purchased a new 2019 SLT with the X1 package. It has the Red Quartz Tintcoat paint. I usually never leave reviews, but honestly this is the most comfortable, nicest loking truck I've owned , and I've ownwd alot of them. The only issues I've had was the brake software was flawed, took it to the dealer on recall and they installed a new software patch, Other then that I love the styling, performance and the interior is very nice. No regrets

"THE" GMC Truck!
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.

We are return customers to Mountain states Toyota.
We are return customers to Mountain states Toyota. In 2018, we bought our RAV4 and were very pleased with the experience that this time we decided to buy a 2025 plugin hybrid. We found Mr. Matt West was extremely welcoming and made the whole process a very meaningful experience. He was very knowledgeable and patient and was willing to answer our questions to our satisfaction. We continue to recommend him and the Mountains states dealership several of our friends. We wish Matt all the best.
Great truck!
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!

I recently leased a 2025 Jeep Wrangler and the entire experience was great. Aydin was professional, thoughtful, and worked to get me what I wanted. I highly recommend this dealer ship to anyone looking for a car.
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

My 2016 GMC Sierra 1500 SLT All Terrain - Love it!
I've owned this GMC Sierra 1500 All Terrain since it was 8 months old. With the exception of two warranty issues (failing power brake vacuum pump and transmission electrical harness), I have been totally happy with this truck. Up until now, my 1996 Chevrolet K1500 Silverado with it's 5.7L Vortec engine was my favorite truck of all time, this GMC (5.3L LS engine, 8 speed automatice) has earned the top spot now of my all time favorite truck. It is comfortable to drive, and runs as good as the day I bought it over 5+ years ago. I've got 71.5K miles on it. My biggest issue is I wished it had the 6.2L engine for better towing capabilities. Other than that ... love this truck.

Excellent and reliable, only thing buyers have to do is buy a AFM disabler that you can stick into OBD2 port to avoid lifter failure (longer story, nobody wants a V8 to run in V4)

Awesome experience!
I was looking for a specific Ford Truck, a F350 Diesel. I found one on Cars.com that was at Interstate Ford. I live about 2 hours away from the dealership. I contacted Ryan Huber, one of the AMAZING sales reps there, by email. Ryan emailed me within minutes of my inquiry about the truck I saw and made an appointment with my that day to see the truck. Ryan was great! very low key, no nonsense, and helpful. not only did he show me the truck, he helped me through the purchase, financing, and final delivery, coming in on his day off so i could complete the purchase and pick up my NEW TRUCK! Thank you Ryan!! and Thank you Interstate Ford! You folks know about good customer service, valuing my time, and are extremely helpful and knowledgeable! Ryan, you are the best! if you need a new truck or car, Ryan is your guy!

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!

Worth the wait to finally have it
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

Foundation Cadillac did it again—and honestly, I’m not surprised! When my 12V battery died on my Cadillac Lyriq, David Hann and his incredible team jumped into action. They did whatever it took to get me back on the road quickly and stress-free. David is truly amazing—always professional, caring, and reliable. If you’re ever in need of service, repairs, or even looking to make a purchase, go to Foundation Cadillac and ask for David. You’ll be in great hands!
