9. 2012 Dodge Challenger
Average paid: $24,310
This is the first of the trio of American road-friendly sports cars that are driving Detroit's muscle car renaissance. The Challenger was rereleased in 2008 after a 25-year hiatus, but already keeps up with rivals such as the Ford (F - Get Report) Mustang and Chevy (GM - Get Report) Camaro. Its base V6 engine produces an impressive 305 horsepower, but its beastly 6.4-liter hemi V8 cranks out 470 horsepower. Even with all that power, it still has enough room to fit a family of four comfortably with a load of groceries in the trunk. Think about that the next time you snicker at a stick-figure family sticker in a Challenger's rear window.
