We are from Colorado and were in Utah seeing some grandchildren. The water pump and radiator went out in our GMC Sierra Denali. Brittany Holt at National GMC fit us into the shop’s busy schedule and we were able to get the repairs completed and were on our way home the next day. She is a professional service advisor and she and the team deserve a 5 star rating. Completely first class customer service. Thank you, Brittany!

I had my truck serviced here today. These folks are awesome! JD is amazing. He checked me in and got things rolling right away. He’s professional and knows exactly what needed to be done before I had to ask. He kept me updated, via text messages every step of the way! I won’t use any other dealership or service provider.

Went in for a oil change and tire rotation. They told me I needed a filter next thing I know I have a bill for $300 what a rip off. Next day I get my carfax report I hadn't filled my tires that were down a little because I was bringing it in for a rotation. I looked at my carfax it said they hadn't even done it. What other work do they say they do and don't. How many people have they ripped off?

Be careful if you choose to deal with this auto group. Look at the reviews , it tells you all you need to know about their reputation and business ethics which are lousy. Glad I don’t need to purchase a vehicle from them. Tried to lower the purchase price of a truck I was selling after we settled on a price. Walk away! I got a great deal on a truck from a reputable and professional auto group !

*** DECEPTIVE PRICING TACTICS *** Contacted this dealer to inquire about a vehicle they had listed on CarGurus - after 24 hours of back and forth trying to negotiate a deal, they informed me that their online price included a $3,500 "rebate" for financing the vehicle with them and that the price would go up by $3,500 if I chose not to finance with them... On top of that, the truck in question is $10,000 OVER dealer book value! Meaning, their own finance department would require $10k down just for it to fit within a 120% LTV cap... ABSOLUTELY INSANE!!!!!! Don't buy from dealers that play games with their prices. The price listed should be the price regardless of how you choose to pay.

I was not going to write this review but they went out of their way and earned every bit of a 1 star review from their service department. I think it's important that other customers know what to expect when they decide to do business here. I had 2 different vehicles that I brought in for service and the exact same thing happened twice. First I had to wait 2 weeks just to get the appointment and when I dropped it off it wasnt being dropped off to work on it, it was being dropped off the sit there for 3 weeks. I had to handle my own rental car arrangements and pay for and get reimbursed from General Motors. I had to pay out of pocket for some items that weren't covered but the warranty (programming) which I understand that. The programming issues that I paid for didnt even get fixed and are still a problem. I called in and asked for the owner who told me he would get right on it with the service manager and I never heard a word back from him or anyone else. I heard excuses like out techs quit or called in sick and anything else that they wanted to blame it on. After a month of it being there I finally got it back. Vehicle 2, thought I would give them another chance. Once again set the appointment for a week and a half later and dropped it off for the appointment and here we go again. No call backs about what was going on so I made numerous phone calls to see what was going on after a week of it sitting there. I told then what I thought it was but I'm not a mechanic. They diagnosed it and changed the front cv axle and we picked it up after 2 weeks and the problem wasnt fixed so we took it right back. Spent $800 on that trip. They then put it on me that they replaced what I THOUGHT was wrong with it (once again, I'm not the mechanic that diagnosed it) Turns out it was a rear wheel barring and back brakes making the noise that they heard the first time they looked at it. Here goes another $1200 to fix that part. That car was there for 6 weeks total and once again they blamed it on techs quitting and calling in sick and I am the one that had to continued to call back multiple times to get an update. After no returned calls I drove in to the dealership to ask them why they would call me back and what is going on. They never held themselves accountable for any of the issues and simply didnt care about taking care of the issues which I paid for again. Go here at your own risk and expect your car to sit there for a month and dont expect any communication from anyone there. Lesson learned after the 2nd chance.

Beware = Unethical and criminal- I experienced bad faith lies, contract padding, theft of down payment, refusal to fix their errors.

After I found truck I liked on lot I was met by Micheal's took me on the worst vehicle bying experience ever, I started with a 680 fico now I have a 610 because they hit my credit so many times ,now the truck quality was good except the had another detail rv shop remove headlights and paint inside reflectors to match body color and reinstalled so when you go to car wash they fill up with water and head lights burned out! So I would also get your own financing being they sold me a 4500 warranty on top of the factory 5yr warranty for no other reason than pure greed and profit motive which is worthless !! Run don't walk from here!

DO NOT GO HERE!!! We just bought this truck over the phone from CO. Saw that they had the TPMS sensor going off in the pictures. Asked them to fix it. When we got there it wasn't done. So we asked them to get us a 7 day warranty where they will cover it when we got home. when we got home, and went to a place to look at it, they ghosted us. We paid 150$ to get it looked at and no results. Its still a bad sensor and all they sent us is a google screenshot of how to do it ourselves instead of covering the repair using AI. They have horrible customer service. Mike treated us like trash when we got there.Threw a pen at me for asking about the warranty. Spencer helped us over the phone and then ghosted us when we needed help with the sensor. Always saying he'll speak to the GM to get this covered. AVOID THIS PLACE!!!! Hidden problems in the vehicle.

Do not buy from this dealership. Bullied into a 24% interest rate and told this was my only option. Told them i wanted to leave three times but bullied to stay. Spencer told me he would get me a great deal and doubled the interest rate my credit union was able to get. I don't even have possession of the vehicle never have they just took the down payment and ran. This is a predatory dealership that in addition to an outrages rate added double the fees into the loan. Reporting to any agency I can they need to be stopped.

Service department doesn’t communicate. I’ve been there for my car 6 times to fix a screen that wasn’t working on my brand new Yukon and we had brake issues that I paid to replace and now I have to pay to replace them again 1 month later. They are the worst.

We had the privilege of working with Spencer. He worked really hard to find the perfect car for us. Even going to lengths of bringing a car in from a different location. He helped us get a great deal on our trade in and new car and we couldn’t be happier. Thanks Spencer!! Curt and Josh were also great to work with! We are very thankful for everyone that helped us in the car buying process. Definitely would recommend!!!

It took a bit of back and forth, but ultimately I was able to purchase a 2016 chevy colorado for listed price with a detail, new tires, new windshield, and a second key. Drake and Drew were the sales reps that I worked with, they were quick to get me 6.99 on my loan at a time when rates were generally closer to 8.

Everyone was super friendly! Jake helped walk us through the lot. He was very helpful in explaining differences in vehicles. He took the time to show us a few different finance options as well. Not pushy or rude like most dealerships. We feel like we scored with our truck!

Just want to say we've been to a couple of dealer before we were even greated but we came here to national Buick and Jason Omar didn't hesitate come great us and offer us assistance. We appreciate his customer service and he went above and beyond!!!! So we ended up purchasing a vehicle!!!!
