Almost glad I broke down so I could meet some of the most
Almost glad I broke down so I could meet some of the most friendliest people on the planet, if everybody gave service like that, they would be a lot more smiles around. Thank you very much for your kind polite service. The only shame is they don’t have 10 stars to give you.
This is a luxury suv with plenty of room.
This is a luxury suv with plenty of room. I'm still learning the features. It is a smooth ride with a great interior. Great for towing a popup camper.

2021 Yukon XL Denali Diesel 3.0
This Yukon XL has exceeded our expectations. We upgraded from a 2014 XL and it's like apples and oranges. From a size standpoint, the new design allows my 6'6 son to sit in the 3rd row. Not possible on the 2014 xl. Also, they have upgraded all of the finishes and with the new 10 speed tranny the XL drives and feels amazing. We also opted for the 3.0 diesel as that's what was available. We didn't even test drive one as they are hard to find - but man are we happy with the engine, gas mileage, and just how quiet it is. In city driving we're getting about 22 mpg, and then on highway expect to get about 27. Safety features and heads up display all work great. And, the sunroof thing is amazingly huge. Well done GMC and I highly recommend the Yukon XL to anyone that needs to move people in comfort. :)

Easiest Car Purchase To Date
I was searching for a new/used car. I used Cars.com to search for a Toyota Highlander. Carmax in Ft. Worth, TX was one of my choices. The car shown online was EXACTLY as shown when I saw it-the pics and details provided about the car were so accurate, there wasn't a need for alot of "wheeling and dealing". I emailed Carmax regarding my interest, late at night. Not only did I receive an email within 1 hour, the next day I received a phone call from Mr. Ben Arbour, the person who would eventually sale me the car. He walked me through their process, got me pre-approved over the phone, so that all that was left to do when I got to the office was to get the trade-in value on the car I was trading, test drive the new car & sign paperwork to purchase. I bought a 2010 Toyota Highlander that was a 1 owner car with approx. 13,700 miles. I recommend Carmax to anyone looking to get another car. They were great!!! The customer service is GREAT!!!

I had an outstanding experience purchasing my 2020
I had an outstanding experience purchasing my 2020 Mercedes GLC 300 at AutoNation Ford South Fort Worth! From start to finish, the process was smooth, transparent, and stress-free. A big shoutout to Tyler Morgan, who was incredibly helpful, knowledgeable, and genuinely made me feel like a valued customer. He answered all my questions with patience and professionalism, and never made me feel pressured at any point. The vehicle was exactly as described — clean, well-maintained, and priced fairly. I couldn’t be happier with my purchase or the level of service I received. Highly recommend Tyler and the team at AutoNation Ford South Fort Worth if you're looking for a quality car-buying experience!

Outstanding folks and an excellent buying experience!
Outstanding folks and an excellent buying experience! We worked with Phil to buy a new car for my son and he was AWESOME! The Sales managers were able to offer close to retail pricing on our trade-in to help bring the price down to our budget on top of all the available discounts which they offered. This is great team and I?m very thankful for the experience. Don?t buy another vehicle without checking out AutoNation Ford in Frisco!

Sewell Cadilac of Dallas was Outstanding.
Sewell Cadilac of Dallas was Outstanding. They treated us like an old friend. The whole experience was pleasurable and quickly handled over the phone. All of the details and paperwork was done when we arrived. They took time to explain all of the new vehicle's controls, features and warranty issues. It took about 5 minutes to sign the paperwork on the purchase and we were on our way. i
