Paula and I just purchased a new (used) Infiniti SUV. Diamond Auto Sales staff is top notch! We traded in her pickup in the process, they made this a super fast, easy and great experience. Paula and I highly recommend Diamond Auto Sales for their excellent, friendly, professional sales group!

Saw some cool trucks online so I decided to go check them out in person. Experience with financing and trade-in was seamless. Guys really went above and beyond to make things perfect. The truck I purchased needed new tires. There was mud terrain tires on the truck and they told me they would put on some new all terrains for me. This was told to me by the salesman and the owner alike. Once I got to my tire appt, Kzoo tire informed me they bought the cheapest street tires possible. Talk about leaving a sour taste in your mouth. 2/5 stars.. If they would have kept their word about the tires, would

If it was possible to give them 0 stars I would give them that. I bought a car from them 3 years ago, no issues. Brought in my Ford Edge and traded it in for a BMW X3 that cost me $17,000 in a loan, so… shouldn’t really have issues and they do a inspection on all their vehicles right? Three days after doing so my new car died. I called them and they recommended that I take it into Harold Zeigler on Stadium who works with BMWs to have it looked at. Harold Zeigler gave me a list a mile long of things wrong with this car including the timing chain, oil gaskets, fuel control module, etc

Dont buy from these people. You will think you are getting a vehicle then they will sell it out from underneath you. I spent three days trying to send them info, tried to wire them the down payment since I couldnt be in town to sign papers for four days. They kept telling me I could drive away with the car on Friday but then sold it out from under me on Thursday. Went as far as to give the VIN number and I purchased insurance on the vehicle and sent Diamond Auto the proof of insurance. I will never recommend this company as they are not trustworthy and do not do what they say.
