Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!

This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Ricardo & Aldo w/Huffines are AMAZING!
I worked online with Ricardo Mendoza for a few days via email, he was always prompt and courteous. I wasn't called multiple times a day or pressured to come in, because the car might not be there long. Ya know like you get from most dealerships. When I was able to make it in, he had the car detailed and ready in the event I purchased it. He was very friendly and helpful and worked very hard to make sure I was happy before I left, with a price I felt was reasonable. He even put my license plate holders on my new vehicle. It's simple things and the respect of my time, and no-pressure engagement that will cause me to return to Huffines. Also, when my blue link didn't work I texted him and he responded right back, saying I'd need to return, when I jokingly replied 'ugh' I gotta come back-he had the tech who handles it call me and get me set up and walked through using the app. It was handled within minutes. Most salespersons are done with you the day you walk out with your new vehicle. Ricardo & Aldo w/Huffines are AMAZING!

First time customer in Dallas, Tx
For some reason Mark's name is not on the list where it says, "Choose their name," but Mark was so helpful, patient, explained the process clearly and was very professional. I highly recommend him and would work with him and his team again. I would hope for a promotion for him Hyundai. :)
