Tustin Buick GMC

I had an amazing experience yesterday at Tustin GMC & Buick with Seth R.. I called him the night before to ask about the Sierra EV 2025, and he got right on it! We got the deal done in minutes, charged up the truck, and it was waiting for me to pick it up the next morning because I couldn?t make it that evening. This dealership is incredible! I usually buy luxury vehicles, and the service was just as great as when I do business with Porsche or Land Rover. George in finance was nothing short of amazing as well. The management is doing an incredible job keeping them going because they have such a great team. Every turn was met with a smile, and even in workout clothing, I felt like a valued customer. Thanks to Seth and George, this dealership is now my new pick-up truck home, and I?ll definitely be buying my pick-up trucks through Tustin GMC & Buick in the future.

My son and I recently visited Tustin Buick GMC to purchase a used vehicle. We were greeted by Josh and Guneet who assisted us. Both Josh and Guneet were extremely professional and personable. We were able to negotiate a great deal with a no nonsense approach. I would highly recommend them and the dealership to all my friends and family. Wyatt H.

Avoid Tustin Buick GMC if you expect integrity, transparency, or even basic customer service. I purchased a used Porsche 911 Turbo from them in November, and within days the check engine light came on, revealing an ignition system failure that directly affects smog compliance. This essentially means the dealership’s “passed” smog check was invalid from the start. When I brought this up, they initially refused to take responsibility — until I mentioned California Lemon Law protections. Only then did they agree to begin the process of fixing the issue. From that point forward, I encountered horrible customer service, deflection, and a complete lack of professionalism. I was treated like the problem — not someone who just wanted the vehicle they paid for to function properly. I had to spend my own money on rides and parts while they dragged their feet. One time, they had me sit at the dealership for over 7 hours, did absolutely nothing to the car, and didn’t even offer me a ride home. It wasn’t until April — 5 months later — that I finally had a car I could drive without a check engine light on. Even then, new problems have continued to surface, including a recent oil leak and prior pulley failures, all of which point to pre-existing issues. Despite repeated attempts, I still have not been provided paperwork or documentation for the repairs they performed. If you’re thinking of buying from Tustin GMC — don’t. Their behavior after the sale is disrespectful, slow, and negligent. You might get a car, but you won’t get any support, accountability, or peace of mind.

Guneet and Josh were awesome and made the process a lot smoother. I’m glad they helped me with the purchase of my vehicle and would recommend!

Staff was friendly but i left without being able to have my app hooked up to my car and I was looking forward to that feature

Extremely disappointing experience. I strongly advise against engaging with this dealership’s online sales or inquiries. I reached out to ask a simple question about a vehicle’s availability and was immediately met with a barrage of questions about my trade-in. I complied—providing the requested VIN, photos, and mileage—understanding that this is often part of the process. However, I still never received a clear answer about the vehicle I originally inquired about. The communication was so vague and robotic that I had to ask if I was speaking with a chatbot. Javier assured me he was a real person, though the interaction lacked any sense of genuine customer service. Once I mentioned I would be financing through my own bank, his interest disappeared. He then told me their inventory is reserved for in-person customers only—a fact that could have saved us both over an hour had it been communicated up front. This was hands-down the worst online car-buying experience I’ve encountered. I’ve successfully purchased multiple vehicles through internet sales, and this was inexcusable. I should have trusted the 2-star reviews and avoided this dealership altogether. Best of luck selling the vehicle that’s been sitting on your lot since January!

I am writing to formally lodge a complaint regarding my recent experience at Tustin Buick, located in Torrance (90503). On May 17, 2025, I visited the dealership with the intention of purchasing a 2025 Encore GX. For the past week, I had been in communication with the dealership to obtain out-the-door pricing for both the Preferred and Sport Touring editions. After comparing multiple Buick dealerships within a 50-mile radius of my location, I found that Tustin Buick offered the lowest MSRP. Motivated by this, I traveled 40 miles to finalize the purchase. However, I was shocked to discover that Tustin Buick was attempting to impose nearly $4,783 worth of additional dealer-installed accessories. These charges were not transparently disclosed upfront and were instead listed in fine print above the MSRP, which felt misleading and exploitative. Below is a breakdown of the accessories added by the dealership: 1. Catalytic Converter Etching – $499 2. KARR Security System – $995 3. Appearance Paint Protection – $1,195 4. GMP Theft – $899 5. Forever Start Lifetime Unlimited – $799 6. ClearPRO Door Protection – $396 As a customer, I did not request or consent to the additional accessories totaling $4,783. I asked for them to be removed from the out-the-door (OTD) price. However, the dealership staff firmly stated that these items were mandatory per their policy and insisted I pay for them. I clearly communicated that I only wanted the standard features provided by Buick, without any dealership add-ons. Despite this, they refused to remove the charges and reiterated that I had to pay the full amount. They justified the charges by claiming they are the #1 dealership and need to include these add-ons to maintain profitability. As a non-GM customer, I referred to the pricing listed on the Tustin Buick website, which shows the MSRP for the Preferred model as $18,341 and the Sport Touring as $24,129. I expected to pay MSRP plus taxes and processing fees—nothing more. Since I was being forced to pay for items I didn’t want, I decided to walk away from the deal. Having previously owned Japanese and German vehicles, this was my first attempt at purchasing an American brand. Unfortunately, my experience with the Tustin Buick sales team was extremely disappointing. Their approach to customer service and unwillingness to accommodate reasonable requests left a negative impression. Based on this experience, I will not consider purchasing any GMC or Buick vehicles in the future. It felt like a markup scheme disguised as policy, and I regret spending my weekend dealing with such poor service. In contrast, Penske Buick in Cerritos was transparent about their pricing and did not include any hidden charges. I’m puzzled as to why GMC allows such inconsistent pricing practices across its dealerships. Other brands do not force customers to accept unwanted accessories. This experience has made it clear to me why GMC struggles to compete with Japanese, Korean, and German automakers. I kindly request that Buick/GMC investigate this matter and take appropriate action to ensure that such practices are not repeated. Transparency and honesty are crucial in maintaining customer trust and loyalty, which Tustin GMC/Buick doesnt follow at all.

Dealer add ons are extremely high, we were able to work on some of those numbers. Still high after bargaining, but I agreed since I wanted this truck. When Mariah came back with financing option, I come to find out that we can't finance outside, it has to be their financing or pay cash! Can you believe this? After everything done with salesperson, had to wait for finance. Sat for over an hour &1/2. Employess kept walking in & out of finance office, some eating, while customer just waiting.

We were happy with the service and time it took to complete our purchase. A sales rep (Jerry) worked with us over the phone and had many documents ready to go and prior to our arrival.

Tom & Jerry in real life way better than the cartoon. Got me exactly what I wanted in a reasonable amount of time.
