An unforgettable experience to say the least. This is my 3rd new vehicle and by far the easiest and most hassle free.

Great place and people!
We drove 3 and a half hours to go to this dealership. We could not have asked for anything more, these people are top-notch people. This place was clean, people were friendly and helpful. John O'Connell Was our salesman and we could not have picked a more perfect person to work with. We went in to buy a Yukon AT4, left with the Yukon, and purchased another car from them. We have found a car guy and dealership that will always have our business.

Best experience ever at a dealership
dealerships on how to treat customers!!!! This was the BEST dealership experience we've ever had in our lives!!! Chris Dargan was amazing!!! He was courteous, professional, knowledgeable, and treated us with the utmost respect. Chris never tried to overcharge us. Bert Dutcher was awesome as well!! Bert was upfront about everything and never once did he try to convince us to use their financing. Bert was professional, kind, personal and patient. The only bad thing about Bert was that he wasn't a "Dallas Cowboys" fan!!!! When you're ready to purchase your vehicle and you want to be treated with dignity, come to Rizza!!!
