I recently purchased a used Hyundai Elantra for my daughter from Precision Auto Sales and was happy with both the quality of the vehicle and the level of service provided. The vehicle itself was in excellent condition, exactly as described. The entire process was smooth, transparent, and professional. The salesperson was courteous, knowledgeable, and took the time to answer all of my questions professionaly. The dealership also made the paperwork and registration process efficient and hassle-free. I highly recommend Precision Auto Sales to anyone looking for a reliable vehicle and a good customer service.

Best Car Buying Experience Ever!!
Jose the Sales Manager listened to what I wanted and found the vehicle at another dealership and brought it over. Briana in Sales showed me all the features and explained how everything works. She even helped me get the app set up on my phone. David in Finance was so friendly and made the process easy. I have told all my friends how nice everybody was to me and this was really a no-stress day. I love them. I wish I could buy a new vehicle every year so I can go back over and over.

Same old car dealer tricks
Update, I was quickly contacted by the GM who promised to make good on the car by either getting rid of the smell or take the car back.

Fast service and very professional
I bought a year old BMW. The price was better than I found at other dealerships. They were prepared to go as slow as I wanted and answer all my questions, but that's not what I wanted. I wanted fast! So after a quick test drive went in and signed the paperwork, while they washed it for me. They let me leave my old car there and drive my new car home. There was a headlight malfunction and they said it was completely covered under warranty. However, because it was a software issue, Carmax said I needed to take it to BMW, but that Carmax would cover any costs. They were true to their word!

The customer service, the compassion and understanding
The customer service, the compassion and understanding were truly great. Suzanne and Jason were incredibly kind, very responsive and explanatory and provided us with all around amazing service. We were contacted quickly after our online inquiry and Suzanne was happy to help us answer all the questions we had. We are out of state and the process in which the paperwork and transport of the vehicles were done was flawless. We thank you all for your expertise and kindness. We will be back when the time comes and will most certainly refer all who are in the market to your dealership.
