🚗 1. 2012–2016 Scion iQ

• MPG: 36 city / 37 highway
• Why It’s Overlooked: Its quirky size and 3-door layout turned some people off, but for urban driving, it’s nearly perfect.
• What Makes It Special: You can park this anywhere, it’s got a tight turning radius, and the gas mileage is killer.
• Downside: Not ideal for highway trips or carrying more than one passenger comfortably.

🚗 2. 2009–2014 Hyundai Accent (Manual)

• MPG: 28 city / 37 highway
• Why It’s Underrated: It’s often ignored for being “too basic,” but this generation of Accent is shockingly reliable and super efficient when paired with the manual transmission.
• What Makes It Special: Cheap to maintain, easy to find under $6,000, and great MPG with minimal fuss.
• Downside: Cabin materials are a little bland.

🚗 3. 2012–2015 Chevy Sonic (1.4L Turbo Manual)

• MPG: 29 city / 40 highway
• Why It’s Overlooked: People lump it in with less reliable GM compacts, but the 1.4L turbo/manual combo is a standout.
• What Makes It Special: Sporty feel, turbocharged engine, and excellent highway fuel economy.
• Downside: Turbo maintenance may require extra care past 100k miles.

🚗 4. 2013–2017 Mitsubishi Mirage (Manual)

• MPG: 37 city / 43 highway
• Why It’s Underrated: People hate on it for being underpowered—but it’s one of the most fuel-efficient non-hybrids ever sold in the U.S.
• What Makes It Special: It’s the cheapest way to get over 40 MPG. Parts are cheap, and the car is light.
• Downside: Loud at highway speeds and not built for performance.

🚗 5. 2008–2013 Suzuki SX4 Hatchback (AWD Manual)

• MPG: 22 city / 30 highway
• Why It’s Overlooked: Suzuki left the U.S. market, so these get no attention—but they’re bulletproof and AWD.
• What Makes It Special: It’s one of the few cheap AWD hatchbacks that’s also reliable and available with a manual.
• Downside: MPG isn’t as high as others, but AWD is a huge bonus at this price point.
