Used cars in Frederick, MD

Buying a used car should not mean hours of negotiation or surprise fees at the desk. At Renn Kirby Frederick Auto, our One Time Price puts the best number upfront on every advertised vehicle — online and on the lot — so you can compare, finance, and buy with confidence.

We are a family-owned dealership with more than 85 years of Maryland automotive heritage. That means real people who answer the phone, follow up after the sale, and stand behind the vehicles we sell — not a corporate call center.

Our inventory updates daily with fresh photos and pricing. When you see a vehicle on this site, it is available to test drive today unless marked sold.

Whether you need a commuter sedan, a family SUV, a work-ready pickup, or your first electric vehicle, our team helps you match budget, lifestyle, and fuel type without pressure.

We carry strong Mitsubishi, Tesla, Honda, Nissan, Ram, Ford, and Polestar inventory — with EV and plug-in hybrid specialists on staff who can explain charging, battery health, and total cost of ownership in plain language.

Use filters on our inventory page to sort by price, monthly payment estimate, mileage, body style, and fuel type. Save favorites, compare up to three vehicles side by side, and text us anytime for a quick answer.

Drivers visit us from Frederick, Hagerstown, Germantown, Gaithersburg, Westminster, Mount Airy, Urbana, Walkersville, Thurmont, Damascus, Brunswick, and across the I-270 and I-70 corridors.

Located at 5712 Buckeystown Pike, we are minutes from downtown Frederick and an easy drive from Montgomery County, Carroll County, and the West Virginia panhandle. Out-of-town buyer? We will keep you updated by phone and text so your visit stays under an hour.
