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.
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!

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!

I recently had an exceptional car shopping experience at Auto Boutique. From the moment I walked through the door, the staff was incredibly responsive, addressing all my queries with patience and professionalism. They were genuinely helpful, guiding me through the process without any pressure, ensuring I felt informed about my choices. The politeness of everyone at Auto Boutique was particularly noteworthy; they made me feel valued and respected throughout my visit. I have not yet found a car that perfectly matched my needs but left with a positive impression of what customer service should be. Highly recommended for anyone looking for a smooth and pleasant car buying journey.
