I just purchased a car from Currie Chevy and had an outstanding experience! Miguel gave me a great price and an amazing deal. He went above and beyond to help me find the perfect vehicle, truly listening and understanding my situation while working tirelessly to make it happen for both me and my husband. His professionalism, honesty, and dedication made the entire process smooth and stress-free. If you’re in the market for a new car, I highly recommend visiting Currie Chevy and asking for Miguel—you’ll be in great hands!

I can say I enjoyed buying a car from Covert.
I can say I enjoyed buying a car from Covert. Starting with Jud, every person made me feel more than just a customer buying a car. Each staffer showed genuine interest in me getting what I wanted. I wasn't just a commission or one step closer to meeting the monthly sales goals. And, that is the best reason to buy a car from you. So, thank you.
