Best Kept Secret --- Shhh. Do not disturb the 2009 Hyundai Genesis V6. It may be the quietest car we've ever driven. It would be rude to interrupt it. As Hyundai's newest creation slips slyly into the luxury sedan market, we can hear the silent screams of some other fancy automakers. This car is nice. Really nice. Like why-would-we-spend-our-money-anywhere-else nice. It's the Cadillac of Hyundais.
