Bought used f 250 truck
Great service, took care of me totally, had the truck transferred from another Car Max, they followed it through the purchase and the drive out from the facility.

Gabriel walked me through every step, answered all my questions clearly, and even followed up after the sale to make sure everything was going smoothly. It’s rare to find that level of customer care these days, and it made a big difference. If you're looking for someone who truly cares about your experience and knows their stuff, ask for Gabriel.

I recently bought a 2014 BMW X5 from Hue - he was very attentive and helpful. I had a 3rd party inspection completed prior to purchasing and they gave good marks for the car. I have received many compliments on how new the car looks despite being over 10 years old. The owner, Kal, offered top-dollar for our trade-in and even offered us fair money for an older car. The purchase process went very smoothly with Trice, and the dealership was very responsive when I needed some help with a trailer hitch. Their collection of cars impressed me - they seem to only sell cars in excellent condition. I can definitely recommend America’s Auto Financial to anyone looking for a nicely used car!

We recently bought our second Toyota from Don McGill.
We recently bought our second Toyota from Don McGill. The first was a 2020Toyota Avalon and the second was a 2024 Toyota Crown. The first purchase went off without a hitch and we were very satisfied. The second car (the 2024 Crown) was purchased and delivered on 12/29/2023 with only one key FOB; I was told me I would get a second key FOB in six months. I subsequently talked to the service department; they promptly ordered one and I received it one week later. I do have an issue with the title department. My credit union is threatening to raise my loan interest rate if they don't receive the title. The only way to satisfy my credit union is to explain the process which I do not understand. The dealer should be more proactive in ensuring that the sales process does not end with delivery. My credit union still hasn't received the title. I am forced to keep calling which shouldn't be necessary.

My salesman was excellent . Provided everything I asked for . The sale was flawless . When you have a survey that makes a person write more than what I want it?s ridiculous. You should have the freedom to keep it short and sweet .

I can?
I can?t say enough good things about my experience with Juan, Senad, and Margarita. I have now purchased not just one, but two cars from them, and both experiences were nothing short of outstanding. From the moment I walked in, I felt welcomed and valued. They went above and beyond to make the entire process smooth, transparent, and stress-free. What impressed me most was their professionalism paired with genuine care. They took the time to listen to what I needed/wanted and never once made me feel pressured. I couldn?t be happier with the deals I received. It?s rare to find a dealership that combines integrity, efficiency, and excellent customer service the way Group 1 GMC Southwest does!! I highly recommend them to anyone in the market for a vehicle. This is a team you can truly trust, and I?ll definitely continue to come back in the future!! THEY ARE THE BEST!!!!
