4.2-liter V8, 394 horsepower.  What has four doors, a howling Ferrari V8 and a worse depreciation curve than Chernobyl real estate circa 1986? Why, it's the Maserati Quattroporte. Sure, the Quattroporte's sequential-manual transmission is about as fun as a sick kitten, but just look at that bodywork. Listen to that motor. Smell that leather. Hey, an Italian supermodel with a peg-leg is still an Italian supermodel.
