Amazing experience! Steven Verizzi was wonderful to work with. This is the third time we bought a vehicle from Emmons Autoplex, second time that we worked with Steven Verizzi and we couldn’t be happier, he is absolutely amazing! And their coffee machine is great too.

I had a great experience at AutoNation CDJR Katy.
I had a great experience at AutoNation CDJR Katy. Rafael was my sales rep and he explained everything clearly, answered all my questions, helped me feel at ease about any doubts I had regarding making a big purchase, and worked hard to make sure I felt comfortable with the best deal they could possibly get. Gerardo in finance was just as great. He was knowledgeable, very easy to work with, and even made signing paperwork fun. The whole process was smooth and efficient! But what really stood out to me from this dealership was the degree of professionalism and honesty. When an issue came up, instead of brushing it off, they were upfront and fixed it quickly. That kind of integrity and proactive protection of customer trust is rare. And it?s the reason we?ll definitely come back here for my husband?s car and my next car, as well as refer my friends and family, because outstanding customer care like this deserves to be shared and celebrated. If you want an honest dealership that treats you with respect, values transparency, and truly cares about its customers, AutoNation CDJR Katy is the place to go!
Great Buy!
This truck is amazing. Turning heads all over as we tour the area. Those riding with is also enjoy the comforts and safety features. Great Buy!

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.

My experience with Dean Motor Cars was nothing short of
My experience with Dean Motor Cars was nothing short of exceptional. From the very start, Ahmad made me feel genuinely cared for — not like just another customer. He was upfront, transparent, and quick to answer every question I had, which made the whole process smooth and stress-free. What really stood out was the personal level of service. Ahmad took the time to understand what I was looking for and made sure I felt confident every step of the way. There was no pressure, no hidden surprises — just honest communication and real professionalism. If you’re in Houston and looking for a dealership that values transparency, care, and responsiveness, Dean Motor Cars and Ahmad are the team to see. I couldn’t recommend them enough.

In regardsto fixing a blown fuse on my 2024 sierra 2500.
In regardsto fixing a blown fuse on my 2024 sierra 2500. Diagnosis for $250 was applied to the bill for fixing the item which was basically a wash as the labort to remove a few exposed nuts on top of the battery cost about the same. But the repair allows me to keep my factory warranty, and for $600 after a generous $50 discount, I will sleep well knowing GM had my back.

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!
