SLK320, with a 215-horsepower normally aspirated V6, is $44,800. It adds the V6 engine, wood trim for the interior, power seats and a telescoping steering wheel. New for 2002 is a redesigned Sport option package ($4,200) for the SLK230 and SLK320 that includes side sills, a front air dam, rear fascia, projector-beam fog lights and AMG alloy wheels. The first thing you notice about the SLK320 is the wonderful sound when the engine starts. Mercedes designed the exhaust system to give the V6 version a distinctive, throaty exhaust note that adds measurably to the fun of driving the car without being too loud.
