I just took my truck to AutoNation Ford in Frisco again
I just took my truck to AutoNation Ford in Frisco again for routine maintenance. It’s always been a good experience. The most recent service advisor that helped me was Joshua McCaffrey. I highly recommended this location.

Everyone was great to work with.
Everyone was great to work with. Professional,respectful, courteous and knowledgeable. My salesman Mr. Graver was awesome. He along with the sale manager and finance manager worked with me to give a great deal on the Chevy truck I purchased from them. I recommend Sign It Drive It if you're looking to purchase a great used vehicle.
best in class
My GMC Sierra is the best ride I have had in all the years that I have been driving. I started driving in 1977. I love my new Sierra.

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.

My wife and I were in the market to purchase my son a
My wife and I were in the market to purchase my son a pre-owned jeep, and we wanted something that was already fixed up so we found TCD. They had a great selection to choose from. Once we arrived at the dealership you could tell that this was going to be different than any other car buying experience we've had. Jack was first to introduce himself. He was not a fast-talking silver tongue devil like a "like i probably was" stereotypical car salesman that you might be used to. He was a quiet young man that spoke at the right time and when it was necessary. He listens to our wants and needs and never asked us to remind him over and over! It was a subtle character quality that he possessed, and I didn't think too much about it while we were there, but it was a refreshing quality Jack was very knowledge about the vehicle as well. The vehicle we were interested in was a new trade in, so it wasn't quite ready, so I tell you this to say the way the dealership as a whole jumped in to help get the vehicle sales floor ready, was awesome! You could tell that this wasn't their first rodeo! Next was Tina the GM this gal was on top of her game. Very sweet and accommodating but you could tell on the other side of that coin was a savvy tough businesswoman that was going to be fair but by no means going to be taken advantage of! She settled my early onset buyer's remorse that i could feel brewing with transparency. Mo finished up our car deal and was also the finance guy! I loved that cause once we came to an agreement, we shook hand and started banging out paperwork! Mo was an awesome dude very knowledgeable with all the different extended warranties packages which i never did until we bought our last used vehicle and needed to use it on the way home from the dealer. We were in and out in no time. Lastly the Owner Austin! how cool is it for the owner of the dealership to make himself available to his customers. He personally helped my wife and I with whatever we needed or questions we had. It was nice not to have to wait for a salesman to run ask the manager a question then run back with and answer! By the time he got back I probably had 3 or 4 more question to send him running back with! lol Austin was personable and kind! Which was a breath of fresh air this day in time. This was also after the dealership had closed on a Sat night! A few things that are small but can make or break a car deal is that they had fresh free hotdogs cooking all day with 5 or 6 different flavors of soda pop obviously coffee with one of those fancy coffee makes with different flavors of coffee and cappuccino, clean bathrooms and something as a parent and someone that used to sale cars they had a nice selection of boys and girls toys! if you've ever tried to purchase a car with a bored toddler forget about it! the salesman can feel the words we're going to have to come back without the kids. that's how the dealership down the street with toys just made your customer their latest car buyer! Shout out to Scot and Bryan as well! They weren't involved in my car deal but did a good job at making us feel welcome and at ease! Sorry about them Aggie's buddy! I would recommend #texascarone to any and every one that's in the market for a vehicle especially a young couple that might be first time buyers. These are good folks that i feel like i could trust sending anyone too. Thanks again TCO Brent & Erin Henry 2020 Jeep Wrangler unlimited freedom edition
