They had large variety of cars on the lot that fit my budget. Their customer service is excellent. I never felt pressured to buy a vehicle. They were very informative about all of the vehicles I was interested in. After test driving several vehicles, I chose my Mini Cooper and could not be happier. The sales transaction was super smooth. I have had the car a few months and get excited every time I'm in the driver's seat. This is definitely a family business and they treat you like you are their family. It's so nice to know that there is a dealership out there that truly cares about their customers. I highly recommend Sigma Auto Group for your next vehicle purchase. You will not be disappointed. And I will definitely be returning when I'm ready for my next car!

***(FRAUD FRAUD FRAUD FRAUD FRAUD FRAUD)**** I've purchased…read moremultiple cars from Sigma and Lulu since 2020. Everything always went exceptionally well until my 2018 Ford Raptor needed a new engine and was covered contractually with my extended warranty I purchased through Sigma. Lulu refused to sign the release being that Sigma also owns the warranty company so of course the used car salesmen stepped in! My truck sat at Future Ford for 4 months with no movement and Ford threatened to lien the vehicle and then proceeded to add storage fees. From here Lulu reached out somehow to my ex-wife and the two of them illegally removed the vehicle from Ford and proceeded to hide my truck at Daly City Mitsubishi. I've filed the vehicle as stolen with contra Costa Superior Court being that the truck is illegally being sold now at Sigma Auto. This would be the Lead Foot Gray 2018 Ford Raptor currently on their website. ***DO NOT PURCHASE THIS VEHICLE IT IS MINE AND I'M IN THE PROCESS OF A CIVIL LAW SUIT WITH ALL PARTIES.*** Concord Police Department has been brought up to speed on the matter as of this week and will be engaging to assist. This vehicle is legally owned by Lentegrity Lending NOT MY EX-WIFE this would be the finance company that holds the title. I've personally invested $60,000.00 in cash as a down payment then an additional $15,600.00 in payments as well as an additional $23,000.00 in upgrades. This all legally documented by my sole and personal bank account. ****LET ME BE CLEAR MY EX-WIFE OF 15 YEARS IS BREAKING THE LAW WITH THE ASSISTANCE OF SIGMA AUTO AND LULU ALL IN THE GAIN TO NOT SATISFY MY EXTENDED BUMPER TO BUMPER WARRANTY I LEGALLY PURCHASED WITH THE SALE OF THE TRUCK. (FRAUD FRAUD FRAUD FRAUD FRAUD FRAUD)*** I was also given a loaner car to drive until my truck was repaired as my warranty stated, then as the actions of my ex-wife and Lulu I was threatened that the Loaner vehicle we going to be reported stolen! And I've yet to receive my repaired vehicle back! Again my vehicle is illegally being sold again from where I purchased it and they assisted another party to steal it from under me with a loophole by my stupidity adding my ex-wife to the registration to which she removed my name without my consent .. *****FRAUD FRAUD FRAUD FRAUD FRAUD***** **BUYERS BEWARE THESE ARE SOME OF THE WORST PEOPLE IN THE AUTO INDUSTRY! ** This is grand theft the judge told me, I have court again this coming Tuesday and I will be pursuing all parties with the upmost stern hand of the law including insurance fraud for not honoring my warranty and Sigma Auto now selling my stolen truck right from under me as of current date! I HAVE ATTACHED THE COURT ORDER DENYING THIS PROCESS. THIS COURT ORDER IS A DIRECT VIOLATION OF THE LAW AND ALSO A VIOLATION OF MY CIVIL RIGHTS, and last but not lease FRAUD!!

FIVE STARS IS NOT ENOUGH…read more We had a car that needed repairs that exceeded its value, so we started shopping online for a replacement. We came across a plug-in hybrid that felt perfect for our family...especially with our kids being year-round student athletes, even through the summer. I called Zac Auto Dealers and spoke with Elham, who confirmed the vehicle was still available. We headed over later that morning, and from the moment we arrived, everything just felt right. He came out to greet us. Saw the car right out front and it was in amazing condition, After a quick test drive, Elham had all the paperwork prepared quickly and efficiently. No hassle whatsoever. We decided to finance the vehicle. Zac Auto partners with Travis Credit Union in Concord. Took a short drive there, where we worked with a gentleman named Herman. He mentioned he regularly helps Zac's customers, and it showed. He made the entire process smooth and stress-free. Travis Credit Union was so welcoming and professional that we even opened a savings account with them. We picked up the car the next evening at Zac's. We were told it had been serviced and checked at their partner shop, Ace Auto Care in Lafayette. The car was in pristine condition. It looked, smelled, and drove like new. About three and a half weeks later, I noticed white smoke coming from a small tube underneath the car. Long story short, it turned out to be related to the battery/heating system. The car still drove perfectly, but not knowing who to call, I reached out to Zac Auto for guidance. A gentleman, Aziz, answered and without hesitation reassured me: "Don't worry...we'll take care of it." I explained what was going on, and he immediately directed me to bring the car to their partner shop, Ace Auto Care. At Ace Auto Care, I received the exact same level of service: kind, friendly, professional, honest, and incredibly respectful. Felt like I was greeted by cousins. By the very next day, my car was ready, repaired with brand-new parts...courtesy of Aziz and Zac Auto. Honestly, between Elham, Aziz, Herman, and the entire team at Ace Auto Care, it truly felt like we hit a grand slam. Thank you, Zac Auto Dealers. You are all a true example of how a business should be conducted along with how people should be treated. You didn't just take care of a transaction and a pricey repair...you took care of our family, and that means everything. Thank you.

About a Subaru outback and it has ran great. My second purchase was a toyota sequoia. Zac Auto has gone above and beyond once again with their customer service. They are honest and upfront, and they make it clear that they want the vehicle to be a good vehicle for you when you purchase it. They stand by their cars and if there's any issues, they take care of it. It's rare these days to find a family dealership with this integrity and care for their customers. I would send anyone in my family there without hesitation and have recommended them to several people. Anytime I need a new vehicle I will go straight to Zac Auto. If they don't have what you want, they'll find it for you. I can't thank them enough and we'll be back again. I'm sure.!

A huge thank you to Viva, who made the entire experience unforgettable. From the moment we arrived, she made our test drive so much fun. We spent time talking about our careers, shared some great conversations, and she was 100% honest, genuine, and never made us feel pressured. It truly felt like she cared about helping us find the right vehicle, not just making a sale. We even had a great time bonding with the rest of the sales team while watching the FIFA World Cup game, which made the dealership feel welcoming and relaxed. Her manager was equally professional, and the entire team kept their word throughout the process. They genuinely take care of their customers. The purchasing process was incredibly easy, fast, and mostly virtual, which made everything so convenient. Of course, there were a few terms to work through to finalize the deal, but they were understanding, fair, and willing to work with us to make it happen. As first-time Porsche buyers, we couldn't have asked for a better experience. Thank you, Viva and the entire Northgate Auto team, for making this such a memorable milestone. We absolutely love our Macan S!

From start to finish, the negotiation process was fair, transparent, and refreshingly stress-free. They took the time to listen and worked with me to reach a deal that felt right for everyone. What really stood out was their commitment even after the sale--any minor vehicle issues were addressed promptly and professionally, which gave me great confidence in my purchase. Most importantly, this experience resonated deeply with my teenage daughter, who was with me throughout the process. It was her first time being part of a car purchase, and Moe and the team made it engaging, educational, and genuinely exciting for her. That alone made the experience even more memorable. If you're looking for a dealership that combines professionalism, integrity, and a personal touch, I highly recommend working with this team. The Morales Family.
