    Nobody around part 1 GMC.
    Ryan O.

    I'll own it: I'm a bit particular. Not "difficult," just the type who reads the fine print and expects the headline price to be the price. No test drive, no trade-in, no financing gymnastics--I wanted the advertised 24-month lease and to pay it in full. That should be "easy mode," right? Reader, it was not. If you've ever ordered a pizza online for $15 and had the driver show up asking for $25--plus a mandatory "anti-theft pizza lock"--that's basically my weekend at Costa Mesa GMC. The setup: Sunday around 10:30 a.m., I requested lease pricing for a 2025 Hummer EV. The GMC site showed a 24-month lease totaling ~$15,000. That was the starting line. Spoiler: we did a lot of laps. Communication? Like trying to text a brick. I had to call and follow up multiple times just to get a confirmation. At 12:45 p.m., I finally got a call: "It's about $25,000." No documentation. I pointed out that this wasn't even close to the website price and sent proof. Plot twist #1 (aka "The yo-yo"): At 1:56 p.m., the number magically became about $16,000. Progress! Then I asked for a written quote and spotted a stowaway: KARR security--5 years for $1,045. Not on the dealer site. Not on GMC's site. But apparently on my bill. Why this add-on felt especially wrong: This is a 2025 Hummer EV--a rolling supercomputer that already comes with built-in security features and OnStar/connected services. It's like being sold an "extra seatbelt" at the door of an airplane. The truck already has the safety net; charging another grand for a third-party alarm felt redundant at best and predatory at worst. I said "No, thanks." They said "No, actually." I asked to remove the add-on. The dealership refused because they'd "already taken a significant markdown to get to my price." Clarification: "my price" was the advertised price. "Apply online," they said. "But you still have to show up," they said. I completed the GMC online application around 6 p.m. Sunday. By 10 a.m. Monday, radio silence--then an email from the sales manager at 10:21 a.m. asking how they were doing. I replied quickly. No response. Plot twist #2 (aka "We lost your homework"): After more calls/emails/messages, at 11:30 a.m. I was told they don't receive the application from GMC and I needed to fill out a new one. I did--within minutes. Finally, a heartbeat: After several promised call-backs that I had to chase, I was told at 5:00 p.m. Monday that everything was processed and good. Pickup day, bring a book. I scheduled 12:30 p.m. Tuesday to sign and pick up, asked that everything be ready because I was short on time. I arrived 10 minutes early expecting crowds. There were none--not in GMC, not in Cadillac. A dealership tumbleweed moment. The Hummer? Not charged, not detailed. I waited another hour to even get into the signing office. Plot twist #3 (aka "Now you see five years, now you see three"): Once in the signing office, the $1,045 KARR "5-year" suddenly became a $1,000 "3-year" alarm. Still unwanted. Still unadvertised. Still mandatory. I asked to remove it--again told no, and that the earlier number was "priced wrong." And again--why that's absurd on a Hummer EV: Between factory theft-deterrent hardware and OnStar's connected capabilities (you know, the stuff built in so you can ping, lock, locate, and get help), selling me a bolt-on alarm felt like charging admission to use the door handle. The truck already speaks fluent "security." Credit where it's due: Abraham and Berenice were kind and tried to help. It felt like they were pushing a boulder uphill while the back office kept greasing the slope. The finale (cue confetti cannon that jams): I did get the vehicle I love--from a dealership I would not recommend to anyone. The "brand new" car had minor scratches, dents, and interior imperfections--like it spent the night wrestling a shopping cart.

    On January 23 ,I dropped my truck off to have the breaks done .Made a appointment for Saturday service, they confirmed that I had a 8A.M. appointment. They informed at 4PM that my truck would not be ready until Monday at 10 A.M.,I picked my truck up at 10 ,they gave me $20 off for the inconvenience. I proceeded to drive off their property .After making 2 left turns on to Harbor Blvd., getting up to 40 MPH the left rear wheel fell off. They didn't put the lug nuts on, the tire proceeded across the medium and struck another car head on. Luckily no one was hurt .It's been over 9 weeks , I haven't got my truck back from them. You would think the last thing they would want is a Yelp review like this.No one calls to give me a status; just say they're waiting on parts .

    Typical bait & switch by the team at Costa Mesa GMC. Attached AutoTrader photo shows their current advertised price. I called ahead of time to assure there wasn't a catch or added accessories required to purchase. There wasn't according to them. BUT, pricing had suddenly changed, and "auto trader is a 3rd party and they had it wrong,".... Then it changed to supposedly the pricing was expired from last week and not updated on the site. Somehow their pricing went up at the end of the month while their advertising "Black Friday" blowouts on their website. Be aware of this dealer.

    The truck the this dealership didn't want to sell and I bought from a much more reputable dealership.

    Update....again...dealership continues to call even after ive stated how horrible this dealerships tactics are. I've written a review AND updated it and yet they continue to call. I do not recommend this dealership.

    Well, my beautiful GMC terrain AT4 kept telling me I was due for oil service lol. I actually purchased my vehicle through Boulevard GMC in Long Beach, but decided to try out Costa Mesa GMC because it was closer to me. I'm glad I did! The service was five star from the initial phone call to schedule my appointment, to drop off and check in, to phone communication and pick up. Jessica in service was wonderful and they even washed my car before pick up! This is what you would expect from a great dealership with great customer service and I was thrilled. Ignore any of the wishy-washy reviews you may read and go here! Not only was the service five star but the place was impeccably, clean and service oriented!

    I shopped around for a month for a used GMC Sierra and this was the only dealer that got to the point and wanted to get me a good deal. They didn't give me what i was expecting for my trade in but other than that I was in and out with a truck in a little over an hour and happy with the experience.

    Do not buys from them

    I personally regret doing business with this place. I recently purchased a 23 GMC from them last night came in with a Capital One approval and it took them two days to make the deal. The first time I went in they treated me like crap and acted like I wasn't buying when I was already preapproved. Then when I went back the very next day, they gave me the runaround made me run my credit to put another inquiry saying they could beat the rate I have and they could not!! Just put another ding on my credit not to mention the process took over four hours, just to process paperwork. They also would not give me a full tank of gas because they said it's a used vehicle and did not offer me two plates on my vehicle. I would not recommend this place and will never do business with them again be aware of their tactics they just give you the runaround if you don't know what you're doing. Don't listen to anything they say. There a waste of time. And don't deserve your money

    Seems like a management problem... I filled out an online form requesting some info on a Yukon, litterally a week later I can't get the salesman to provide the info I want, what it the out the door price on the car, get asked for credit app, how he can help, but seriously can't provide basic information, I was attempting to "shop local" but major fail. Messaged another dealer, who miraculously was able to provide me what I asked in 15 minutes, and was able to wrap up the transaction and have car delivered within a few hours. Seruously, the insistence on trying to get the customer into the dealer is a major red flag, provide what's asked, it's certainly not like a freaking secret, and you would have had this deal. Total fail on a 90k suv, and quite frankly the reason people hate dealers. Also, despite telling the salesman that I bought it elsewhere and why, still get a daily message about wanting to help.

    Bait and switch type of dealership Have a Trx listed for 61,300 different websites show up they say 69 kout the door taxes and everything 75k

    This salesman told me that I cannot afford the car

To give a little insight, I had taken my vehicle (2018 Honda Civic) to an Auto Shop in my area for a MPI to verify a dealership's findings. They told me there that I needed Rear Brake pads. Long Story short, they 'resurfaced' my rotors and replaced the pads. Brought it in many times and they basically ignored the issue. This other shop quoted me $1.3k for a 'needed' Caliper Replacement to resolve the issue. There I was with squeaking brakes, how embarrassing. That was until I came into contact with this Group, The AutoMedic. The two guys who helped me out were very open and communicative. They found that my rotors were not at all resurfaced by the previous shop. I honestly thought it was included to replace the rotors, didn't know anything about this 'resurfacing'. I knew that I would eventually have to change the rotors after researching resurfacing of rotors. Thankfully The AutoMedic had great pricing! Communication with their team was very helpful. They got me same day, they explained everything and helped resolve my issue. That's my headache gone from squeaky brakes for the last 6 months give or take. Did I mention how fast they got it done? I swear to you, not even a half hour!! From this experience, I would highly recommend going with them. I will definitely be booking with them in the future.

Because of that, I came back for multiple oil changes. Unfortunately, my most recent visit was completely different. I was charged a high price for what should have been a simple oil change and cabin/air filter replacement, and I ended up waiting about two hours for the work to be completed. After talking it through with someone more familiar with car maintenance, it became clear that I was likely overcharged for a job that should have been quicker and more reasonably priced. What made the experience worse was the interaction before my appointment. When I asked for clarification about being told I may need "air," EU laughed at me for asking. I'm neurodivergent and sometimes take things more literally, so I was just trying to confirm whether I was being charged for something that is often free. Instead of explaining, I felt mocked for asking a simple question. Because of this experience, I no longer feel comfortable or confident returning here. I'm sharing this as a caution for other customers--especially women and neurodivergent people--who may not be as familiar with car maintenance and rely on mechanics to be honest, respectful, and transparent.

From start to finish, I was treated with honesty, respect, and genuine care.

That kind of initiative and customer-first attitude is rare these days. Mehdi also worked with me financially, helping to make the repair affordable and stress-free. It wasn't something he had to do--but he did it anyway, and it meant a lot. Carlos, the mechanic who worked on my car, was equally amazing. He stayed after hours to make sure the job was completed today, and he even offered to come in on Sunday if needed. That kind of dedication and pride in his work is something you don't see often anymore. On top of the incredible service, the shop itself is clean, organized, and welcoming.
