2005 Mercedes-Benz SLK55 AMG vs. 2005 Porsche Boxster S - Conclusion - Compact Sport Convertibles Comparison

Both sportsters are supple enough for everyday use on all but the most mottled roads. AMG machines demonstrate their autobahn breeding by delivering rock-solid high-speed stability, and the SLK55, in spite of its compact size and short wheelbase, is no different. The Porsche is stable enough at high speeds, but feels more alive and requires a firmer hand on the wheel.

If the purist's sports-car scale is the measure--as we think it is--the Boxster S is the winner. Its superb mid-engine balance, high cornering limits, scythelike steering, flick-of-the-wrist six-speed manual gearbox, and wailing flat-six are all the credentials a mid-priced sports car could hope for. While clearly an evolution of the original Boxster ethos, it's a better machine in every way than the car it replaces; a controlled evolution as opposed to overstated revolution.

None of this, however, diminishes the SLK55 AMG's considerable, iron-pumping appeal. If the Boxster is an X-Acto knife, this Maximum Strength SLK is a designer meat cleaver. And, man, does it cleave, especially in a straight line, though there's an extra layer of insulation between it and the driver as compared with the Porsche. The Benz's edgier visual statement, trick retract-o-top, faultless high-speed stability, symphonic exhaust notes, industry-leading transmission, and AMG-level of exclusivity earn it a bunch as a first-class choice for a fast cruise across the country--or a slow one, down Sunset.

James Dean would opt for the Boxster, while Clark Gable would go for the Benz. Different guys, different cars, but all are stars, nonetheless.

Hurray for Hollywood.
