CONCLUSION:
1st Place: Honda Civic Si Sedan
Splenda-sweet handling, intoxicating drivetrain and upscale style make it the perfect choice for canyon or caf latte runs.
2nd Place: Nissan Sentra SE-R Spec V
Its great engine and surprising performance are marred by less confident dynamics and cheesy interior gimmicks.
