In any category of car there's always those obvious top-name picks that everybody seems to gravitate toward. Maybe it's me-too-ism, or maybe it's just people's faith in certain apparently "sure-thing" brands.

Whatever the underlying reasons for this phenomenon, in the world of luxury cars, the big names are evergreens BMW and Mercedes, along with more recent fave Lexus.

This all-new M was introduced in Spring 2005 as a 2006 model. It's offered as the M35 with a 280-hp 3.5-liter V6 and as the M45 with a 335-hp 4.5-liter V8. The M45 can also be had in a Sport version, which has 19- instead of 18-inch wheels, upgraded suspension, and a unique automatic rear-wheel steering system. It's this hottest version of the M that we were lucky enough to get for our test session.

Easing into the M45's roomy interior, you're surrounded by high-grade furnishings that speak of expensive quality. Sport versions of the M45 eschew luxury-car-cliche wood trim in favor of attractive stainless steel panels dressed with a fine crosshatch pattern. The cabin's overall look is a confidently understated luxury, with a clean, modern flavor. Very nice.
