The G37 Coupe may be one of Infiniti's most affordable models, but it's the automaker's flagship. It's also the fiercest competition BMW's celebrated 3 Series has ever faced. The BMW holds the crown in driving dynamics, but it's an expensive advantage many buyers might never fully appreciate. The G37, on the other hand, is comparably fast, fun, comfortable and stylish, but with a significant price advantage. There's something magical about the 3 Series, no doubt, but for drivers not likely to explore a car's redline or adhesion limits on a regular basis, the smart money is on the G37.
