Great Experience
My husband and I were in the market for a newer yet used car. We found the car we were looking for on their website and started the process online. Once we got to the dealership, they already had the car pulled up and ready for us to see. We decided we wanted the car and finance worked quickly and efficiently. We had a wonderful buying experience...and AFTER the fact, we noticed a leak by the brakes. They called us in immediately because of that being a safety hazard, put us in a loaner car and have been taking care of us! VERY pleasant buying experience!
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

I went in and they worked with me quickly on the truck that I was looking at and addressed all of the issues/concerns that I had immediately. I highly recommend this place if you’re looking for a pick up.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

For me, shopping for a car is challenging.
For me, shopping for a car is challenging. I've had so many bad experiences with "used car salesman" that I find it difficult to believe or trust anything they say. (beware of Genesis of Mesquite) However, Eunise Medina, Patrick Cahill, Ryan, a BMW Genius, and the staff at BMW of Mckinney, sure made this BMW purchase was a great experience. EVERYBODY was so pleasant, courteous and helpful from the start. They went out of their way to answer questions, showed me printed reports, addressed any concern... I was in their very nice snack area looking for a drink and I muttered out loud, "where's a Coke" and a gent walking by overheard me and said he'd run upstairs to get me one. He was up the stairs and back in seconds with a Coke. I was astounded! The people alone were just great, and the way I was treated so special, it made buying a BMW from this dealership a no brainer. You don't need to shop anywhere else. Thank you, Eunise!
