Tustin Buick GMC review
Hello GMC Team, On February 28, 2026, I posted a review regarding my experience at Tustin GMC, specifically concerning the inclusion of add-ons during the purchase process. In my review, I shared that I felt pressured when I was informed that a protection package valued at $4,200 had to be included in order to move forward with the deal. Today, March 1, 2026, I received a call from Tustin GMC management apologizing for the miscommunication. They explained that it was not their intent to pressure me, and that the final price presented actually included an extended warranty rather than a mandatory protection package. I appreciate the clarification and the outreach from management. I accept their apology and want to acknowledge their effort to address the situation and make things right. This type of follow-up and accountability is what excellent customer service is all about. Thank you to the GMC team for taking the time to reach out. Your actions truly go a long way.

Nissan of Downtown L.A. review
Edi made the process of purchasing our Mercedes Sprinter Van a piece of cake! We drove from Palm Desert to Downtown LA and he had the van ready for us to view and test drive. It took only about an hour to ink the deal. We left for home VERY happy and would definitely reccommend Edi and DTLA Nissan.
2026 GMC Sierra 1500 review
A little expensive, but comfortable, quiet, smooth ride. Great performance out of the 6.2L and better than expected fuel economy in the low 20s. Outstanding interior and good looking exterior, especially in the Downpour Metallic color. I don’t have 700 miles on it yet and have owned it for 3 weeks. Therefore, I can’t pass judgement yet on the reliability, but so far I am very satisfied. This replaced an 8 year old Ford F150 that served me quite well with only a couple of issues in the 100,000 plus miles.

Hardin Buick GMC review
I called the dealership and spoke to Gary Koch. I found him to be very personable and knowledgeable. We discussed the online price and agreed to purchase the car. I am not local and handled the preliminary paperwork over the phone. Once everything was confirmed I booked a flight and Gary offered to pick me up. I was in and out of the dealership in less than 90 minutes. Gary made the car buying process super easy and enjoyable. I also received an exceptional deal.

This is my first GMC and I absolutely love my Sierra 1500 Elevation. The 5.3L v8 is more than enough to pull my camper, I love the stylish interior and it is comfortable to drive. I also felt with the financing and discount specials this was a great deal.

Alex was a pleasure to work with throughout the process. When I expressed my concerns about covid he kindly agreed to wear a mask and arranged for the process to be conducted outdoors as much as possible. He also expedited the sale process because he understood that I needed to drive the vehicle back to the SF Bay Area that day. Lastly, he was very knowledgeable about the Suburban that I purchased, and provided me with a lot of great information about its features and benefits. I wouldn't hesitate to work with Alex again, or to recommend him to others.

We had our truck towed into Hardin GMC for some major engine repairs. Shawn was our service writer and he communicated with us regularly and was clear about all the repairs needed. Once we approved the repairs, they were made nearly a week faster than expected. Overall we are extremely happy with the service we received.

Reynolds GMC review
BEST EXPERIENCE I went to the dealership (at closing time no less) just to look at the models and options expecting to get a used car at a different place. I just needed information for my decision. I even told the sales person (Danny) this and he still took the time to show me through the cars and answer all my questions. A few days later, after more shopping, and bad experiences, I went back and just bought the car new from Reynolds for just a few dollars more than everyone else was asking for used! Every single person at this dealership was courteous, polite, helpful and no nonsense which made getting the truck I wanted that much easier. From sales, (Danny), to Finance (Garrett) to parts (Maria) to service (Khris and Jack) they were all professionals and I appreciate how I was treated. I feel like I found a home for my car business. I will be recommending anyone who asks to go to Reynolds for their future vehicle needs.

Mark Christopher GMC is an amazing Auto dealership. No sales pressure and terrible prices. Johnathon Villa was an outstanding salesman that helped us get a 2022 Canyon Elevation. He took extra steps to help us find the perfect truck for us. We drove over an hour. And so glad we did. Highly recommend. And I want to say thanks again to Johnathon for making the experience great.

2026 GMC Sierra 1500 review
I bought the AT 4 version. Loaded. Has good ground clearance. It's powered with a 3.0 l turbocharged diesel. Has lots of horsepower and torque. I've had no problem but I talked to my friend who's a certified mechanic and they're having a lot of problems with the engine blowing up at very low mileage. A lot of the time less than 15,000. Some of them have problems with the thrust bearings failing causing increased crankshaft play back and forth to the point where the timing chain and the rubber belt that runs the oil pump can fail. The engine has been described as grenading. They're basically self-destructs. There's a specific power code that indicates low oil pressure and allowed rattle sound before it finally fails. I heard that the engines were on back order, so if you're one of the unfortunates you can plan on waiting 10 or 12 weeks or longer to get your truck back. They have to remove the cab completely to swap motors. But overall I love the truck. It's a big improvement over the 2022 I just traded in.

Reynolds GMC review
BEST EXPERIENCE I went to the dealership (at closing time no less) just to look at the models and options expecting to get a used car at a different place. I just needed information for my decision. I even told the sales person (Danny) this and he still took the time to show me through the cars and answer all my questions. A few days later, after more shopping, and bad experiences, I went back and just bought the car new from Reynolds for just a few dollars more than everyone else was asking for used! Every single person at this dealership was courteous, polite, helpful and no nonsense which made getting the truck I wanted that much easier. From sales, (Danny), to Finance (Garrett) to parts (Maria) to service (Khris and Jack) they were all professionals and I appreciate how I was treated. I feel like I found a home for my car business. I will be recommending anyone who asks to go to Reynolds for their future vehicle needs.

This is the second truck from Rudy at Reynolds and I’ve sent another half dozen friends and coworkers who have purchaeee cars there as well. The process is always efficient, the team is knowledgeable, and I have yet to locate a dealer that can beat their prices and service.

Tustin Buick GMC review
Hello GMC Team, On February 28, 2026, I posted a review regarding my experience at Tustin GMC, specifically concerning the inclusion of add-ons during the purchase process. In my review, I shared that I felt pressured when I was informed that a protection package valued at $4,200 had to be included in order to move forward with the deal. Today, March 1, 2026, I received a call from Tustin GMC management apologizing for the miscommunication. They explained that it was not their intent to pressure me, and that the final price presented actually included an extended warranty rather than a mandatory protection package. I appreciate the clarification and the outreach from management. I accept their apology and want to acknowledge their effort to address the situation and make things right. This type of follow-up and accountability is what excellent customer service is all about. Thank you to the GMC team for taking the time to reach out. Your actions truly go a long way.

I had my oil change and alignment done at Tustin GMC and had a great experience. Jose, my service writer, was professional, helpful, and kept me informed throughout the process. Angel, the manager, was also great and made sure everything was taken care of. I really appreciate the excellent customer service and will definitely be coming back. Highly recommend Tustin GMC!

CarMax Palmdale review
Recently I had to get a newer car and believe me I was stressed because of the situation but when I went to CarMax which this is my second car from them it was once again amazing to work with them! I had the pleasure of working with 2 amazing sales associates. Helen Mayo who was my main sales associate and Cheyeene Toliver who helped out my wife and myself when Helen was off! They both were very kind and helpful and made the process an ease! I was thinking of other options but since they were amazing I went with them instead if your looking for a car I highly recommend you ask for either of these two women they are a great help!

Noticed some of the reviews on here for Rollit motors are not good. My husband and I have purchased two vehicles from this dealership and we only have good things to say. We worked with Jaime the two times he was great honest, available and offered great customer service. The two vehicles purchased are still in perfect conditions. I highly recommend.
