I was in for the annual checkup and my salesman Brad
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 truck has a jerk when changing gears sometimes.

I knew what I wanted when in.
I knew what I wanted when in. Tyrell Ford is the best salesman I’ve dealt with in a very long time. He went above and beyond to get us in and out in a timely manner. He was well mannered. I highly recommend classic elite Chevrolet. Best experience ever and I got the car I wanted. They even put a bow on it and took pictures since it was my birthday. Thank you so much Tyrell & Classic Elite. I’m one happy Birthday Girl.

What a fantastic buying experience at Helfman Ford in TX.
What a fantastic buying experience at Helfman Ford in TX. We were shopping online, out of state purchase, and had the pleasure of working with Richard Baxley who went way above and beyond. He kept us informed during the whole process and even more important followed up diligently during the delivery and when we took possession of the vehicle. Of course he then followed up yet again. I tip my cap to the dealership and Richard on a great buying experience!

Made 2 trips to Group 1 Buick GMC North.
Made 2 trips to Group 1 Buick GMC North. Interested in a 2026 Denali. Met Jarvis, my salesman, on first trip and felt very comfortable with him. He is laid back and not pushy at all. Told him what I was looking for and had two vehicles to trade in. I was satisfied with trade in values. Found the truck I wanted, color and interior. Was satisfied with the price quoted and purchased the vehicle. Probably the smoothest transaction I have ever had. Highly recommend both dealership and Jarvis!

I called in regarding a special coverage for my vehicle
I called in regarding a special coverage for my vehicle and was connected with George Avila. George was very informative, polite, and a pleasure to work with. He scheduled me an appointment and communicated with me throughout the entire process. While having to take my car in to be serviced was an inconvenience, he made the process so seamless that I forgot it was even an issue to begin with. My vehicle repair was completed well before the estimate I was given, and he even gave me great advice on future repairs. I also learned that they price match tires which is why when I?m ready to replace them, I?m going to reach out to George and give them my business.
