Harold Harmon opened this lot in 1971 with a handshake and a commitment to honest deals. Today his grandson runs the floor the same way. No corporate quota pressure — ever.

We've watched this town grow — and we've kept pace with it.
Harold Harmon started Riverside Auto Sales in the spring of 1971 with twelve cars on a gravel lot off Route 9 and a simple philosophy: treat every customer like family. Back then, people drove from three counties over because they knew Harold wouldn't steer them wrong.
His son, Dennis, took the keys in 1998 and expanded the lot, added the service bay, and doubled the inventory — all while keeping Dad's handshake-first culture alive. Today, Dennis's son Marcus leads our sales team, and the lot now carries over 200 quality pre-owned vehicles.
Three generations, one promise: honest cars, fair prices, and a deal you can feel good about for years. We carry all makes and models, and we finance everyone — because every family in Millbrook deserves to drive something they're proud of.
Don't take our word for it — here's what our neighbors have to say after buying from us.
"I've bought three cars from Riverside over the years and I wouldn't go anywhere else. Marcus walked me through every option without pushing me toward something I didn't need. Left with an incredible deal on a certified Camry. Honest people, every time."
"I had some credit issues after a rough couple years, and every big dealer turned me away. Dennis at Riverside sat down with me for an hour, worked with their lenders, and I drove home in a clean F-150 that same afternoon. Changed my life. These people care."
"My daughter just got her license and we needed something reliable under $15k. Marcus didn't try to upsell us — he showed us exactly what made sense for her, explained the inspection checklist on each car, and we left with a great Honda. Recommend to everyone."
