I’m looking and have been for a while.
I’m looking and have been for a while. I have found most car sells men don’t care what they say to sell a car. I was pleasantly impressed with a young man by the name of Luke Fox when showed me the cars and all that entails. When I make my final I hope I can buy it from Mr Fox. Thank you Luke
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

Same old car dealer tricks
Update, I was quickly contacted by the GM who promised to make good on the car by either getting rid of the smell or take the car back.
2021 GMC Sierra Denali
This is the nicest truck I have ever owned. Lots of features. Takes a while to learn what all it does but a really enjoyable vehicle.

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!

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!
