Rick made the entire process smooth, stress-free, and enjoyable from start to finish. He was professional, patient, and took the time to answer every question without making us feel pressured. The dealership staff was welcoming, transparent, and genuinely cared about making sure we left happy with our purchase. Overall, it was a great experience and we would definitely recommend both Rick and the dealership to anyone looking for a vehicle.

AutoSavvy Duncanville review
I walked in cold and was in & out in less than 2 hours. Buying a salvage car isn’t without some risk but it can be worth it if you find the right car. I’ll definitely be looking these guys up next time - no pressure, they didn’t waste my time and met me halfway on everything I asked for/about. My salesman Jesus was great - no games, a professional. Daniel in finance made things super easy too. I only have good things to say about the buying process.

My sales professional Michael D'Angelo was very helpful and courteous. He took his time explaining everything and I'm very happy with the deal and car. Highly recommend.
2021 GMC Sierra 3500 review
Has a really Big feel to it. I currently use mine to pull gooseneck trailer. I haven't had a load yet that I couldn't pull. The downsides to this truck is to me I feel it could get better fuel mileage. Also I had trouble with #4 injector...dealership replaced it. Now my AC doesn't work all the time. Although it sounds like it's blowing it isn't.
