Luis was great.

Luis was great. Did all the work for us and gave us a great price. Excellent customer service and took us step by step through the process. He even transferred in another vehicle from another location to have several options to compare. All in all great experience!

Helfman Ford - Stafford review

Outstanding Experience with Amir at Helfman Ford!

Outstanding Experience with Amir at Helfman Ford! I recently purchased a 2024 Ford Expedition Max from Helfman Ford, and I have to give a huge shoutout to Amir for making the entire process seamless and enjoyable. From the moment I walked in, Amir was professional, knowledgeable, and genuinely invested in helping me find the right vehicle. He took the time to answer every question with clarity, and never once made me feel rushed or pressured. His attention to detail and commitment to customer satisfaction were truly impressive. What really stood out was Amir’s ability to make the experience feel personal. He listened to what I needed, offered thoughtful recommendations, and made sure I was comfortable every step of the way. The Expedition Max is an incredible vehicle, and Amir made sure I drove off the lot feeling confident and excited. If you're in the market for a new Ford, I highly recommend asking for Amir at Helfman Ford. You won’t just get a great car—you’ll get top-tier service from someone who genuinely cares.

I was in for the annual checkup and my salesman Brad Biondo had reached out to me via email with an assessment of my 2020 car. So I stopped by. Ha- now driving a 2026. That wasn’t the plan. I continue to be impressed with the upgrade. Huge difference in performance and attributes. Brad made it all to easy. Super knowledgeable, reliable, with integrity- highly valued.

This review is about our car buying experience with Mr.

This review is about our car buying experience with Mr. Keith Mack. we are beyond blessed and grateful for all of your hard work in helping us to get the car of our dreams. You are a class act; very patient, kind and a master at your craft. Your whole entire team is by far, the best in the business. You and your team made this car buying decision one of the most memorable, meaningful and important experiences we have ever had. For anyone who is interested in buying their dream car, family car, any kind of car you will NOT receive better service than you will get from Mr Keith Mack and team at Group 1 GMC. Last, but not least our vehicle was listed well below the average market value. Not only did we get the car we wanted, our vehicle came fully loaded, washed, detailed and with a full tank of gas. Mr Keith Mack is the only salesperson you will ever need, so tell your family and friends; you will not be sorry!

Auto Boutique Texas review

Very professional, great group.

Very professional, great group. Last Tesla I bought was purchased from a group that sells 50-65 teslas a month (idrive in Carrolton tx). Auto Boutique surprised me, and managed a Tesla sale like a group that sells 10x more of these technically challenging vehicles. They got the car added to my Tesla app quickly and I left the dealership able to supercharge and drive 6 hours to my home. The young guys ( Ethen Beck and Enrique Ovalles) were very Tesla literate. I'm a contributor to a tesla owners forum and have over 4 million content views, so I'm not a Tesla Newbie. I have a 2016 model s p85, a 2021 model y dual motor, and now a 2021 refresh model s long range to replace the aging ap1 car. These guys had the recurrent battery report in addition to the carfax so I could skip checking the battery. Staff went into service mode and we checked the error log. They got an update to post before adding the car and so I drove off in great shape!

Big Star Chrysler Jeep Dodge Ram Fiat Clear Lake review

Used 🚙

First experience working with Big Star Chrysler we’ve always gone through Big Star Honda. From the moment we entered it was like we found our second home dealership wise! Manny was our salesman and went above and beyond to take care of us. Though it was a used car Manny made sure this vehicle was worked on and like brand new before we drove off with our Sequoia. Big thank you to Manny! I wouldn’t trust anyone else!
