Dodge Neon SRT-4

Introduced in 2003, the SRT4 was one of the best and cheapest performance cars in America at the time. The compact Neon can turn into a pocket rocket with a 2.4-liter turbocharged four-cylinder with 230 hp, propelling Neon to 5.4 seconds from 0 to 60 mph (via Car and Driver).

Of course, almost every owner tuned its Neon SRT4 the minute it left the dealership, and some owners even managed to squeeze over 400 hp from the 2.4-liter engine.
