The Infiniti G25 sports sedan offers almost everything the top-rated G37 does but costs less.
The G25 is agile and fun to drive.
Further, its interior is well finished and fairly quiet.
Definitely skewing toward the sporty side, ride quality is taut, composed and comfortable enough -- but not exactly luxurious.
With its smaller V6, the G25 is noticeably slower than the G37, but gets substantially better fuel economy.
