Look no further
I highly recommend this dealership, it's always a great experience purchasing a vehicle from them. Anthony goes out of his way to find me what I'm looking for within my price range, can answer any questions I may have about the vehicle, and is always willing to help out. I just recently purchased another vehicle from this place and I'm enjoying it so far, no complaints.

We found our vehicle on line and messaged about it.
We found our vehicle on line and messaged about it. We were told it was sold, However, the next day we got a call from Hunter stating that it was in fact, not sold and to come as soon as we could. He had the vehicle warmed up for us and ready to take on a test drive. Cory Who is the sales manager was also wonderful to work with. Holly and their finance department is an amazing person. I would recommend anybody who needs a car to go to Heller. When you buy from them, it’s like you’re buying from family.

Very pleased with the entire buying process at Leman's Chevy. Carson was great, he sent us a personal video of the vehicle and it was just as he described once we arrived for the test drive. Carson met us there on his day off and helped us through the entire process from the time we walked though the door.

Nick Fisher and Johnny Lane were both EXCELLENT to work with! Not once did we feel pressured or confused in the process of our purchase. These two are an asset to the business. We’ve been purchasing cars for over 50 years in more than one state and have never found the experience as pleasant as our experience with these Sam Leman associates!
