If you’re looking for a used car under $9,000 that won’t make you dread long highway drives, you’re in the right place. I’ve put together a list of fuel-efficient cars that hit at least 35 MPG on the highway, are easy to maintain, and are actually findable in today’s used market without breaking your budget.

These are practical choices if you’re commuting, road-tripping, or just trying to cut back on gas expenses in 2025.
Why 35+ MPG Matters
While hybrids and EVs are becoming more common, there’s still huge value in efficient gas-powered or hybrid cars that don’t need a plug. Cars that get 35 MPG or more on the highway often mean fewer fill-ups, lower emissions, and more money left in your wallet each month.
