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.

Great Service!!!!!
I truly enjoyed my shopping experience yesterday on Friday. October 2, 2015. Mia was very patient, professional, and caring in listening to my needs and concerns. With God's and Mia's help I was able to purchase a 2015 Ford Focus. Thank you again Mia for being an excellent salesperson. I will definitely recommend CarMax to my friends.
