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.

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.

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.

Auto Republic Orange review
After getting the run around from multiple dealerships in LA/OC/IE I visited Auto Republic. Yes, I had my guard up after all the financing and heavy down payments other dealerships we're asking for before even giving me attention. The showroom was clean and the lot had so many dream cars. I found the perfect car for my family and had the assistance from the manager that was top notch. I'm writing this review since the single star reviews show the lack of reading details about add on features. Don't get upset with a dealership for having tracking on a car (saves on insurance) along with other key options that are great for your next car. I've referred family and friends, all had exceptional purchasing experiences and I'll get my next vehicle here as well.

I had a great experience at Auto Source in Banning, CA. The staff was friendly, honest, and never pushy. They took the time to answer all my questions and made the whole process smooth and stress-free. The selection of vehicles was solid and fairly priced, and I felt confident in my purchase. If you’re looking for a reliable dealership with great customer service, I definitely recommend Auto Source.

Royal Auto Dealer review
We managed to come to an agreement and purchased the car we wanted. There was not much negotiation, but the car was well priced to begin with. We agreed to pay $500 additional in order to drive the car away and have our mechanic inspect it. We got a week to report any issues and could return the car for a full refund if not satisfied by any necessary repairs. Ultimately the car checked out and the only problem was a piece of windshield trim that flew off on the way home. We negotiated a $200 refund and got the repair done by our mechanic so we didn’t have to drive the car back to the dealer. So far, so good.

CarMax Serramonte review
I had no choice, my car of 20 years, which I bought brand new in 1999 was done. With so many websites ( I looked at several), I was not sure where to go. Then someone mentioned Car Max to me. I looked on line and saw a few cars I was interested in. The next weekend I drove to Colma to checked out and test drive a couple of cars. I decided to ask about Hybrids...you had 2. I test drove one of them and could not resist. I bought it. I was very impressed with the buying process. It was quick, easy and believe it or not relaxing since the sales person completed the paper work for me. Yes, I had to sign several sheets but that was a given. Something I was dreading for the past two years, was so surprisingly easy I couldn't believe it!!!

Laguna Niguel GMC review
On April 6, 2023, I took delivery of a 2023 Yukon Denali Ultimate, which was a SUV that I ordered, equipped the way I wanted it. John and the entire sales staff were great! I have purchased/leased 4 other vehicles from this dealership and have always been treated well. If you want to avoid all of the seemingly normal drama that goes along with walking into a dealership, you need to try this one - you'll be pleasantly surprised.

Auto Republic Fullerton review
Much Better Than Expected! Worth the Drive. Purchased a 2014 Toyota Sienna I drove several hours to this dealership to check out a specific 2014 Toyota Sienna—and I’m really glad I did. My salesperson, Chris, was outstanding from start to finish. He was extremely responsive, easy to work with, and genuinely honest. He answered all of my questions quickly and clearly, and was very personable without being pushy. The car was exactly as described, and the buying process was smooth. A day after I brought the Sienna home, the check engine light came on. I was obviously concerned since the sale was already finalized, but Chris immediately told me to bring it back in. The dealership diagnosed it as a faulty sensor and replaced it on the spot with OEM parts at no cost. That kind of post-sale support is rare, and really impressed me—they stood by their product 100%. One thing to note: there are dealership fees totaling about $1,400, which in my case were not negotiable, HOWEVER, the fees do include services like LoJack protection and a paint/interior protectant, so there’s actual value provided—not just markup. Also, if you look at the bottom of the ad, the dealership does mention that they are included. Overall, I’m very satisfied with my experience. The car is running great, the team was professional, and Chris went above and beyond. My experience was much more positive than the online reviews led me to expect. If you're considering buying from this dealership, I highly recommend reaching out to Chris!

Chevrolet of Montebello review
Carlos Corona was very patient while my husband and I were trying to make up our minds. He answered ALL our questions regarding each car we looked at. He gave us time to think about our chose. We were very comfortable with him. He did NOT pressure use at any time. Would recommend him to anyone looking for a car to buy.
