The CLK500 Cabriolet is close to flawless. It delivers fierce acceleration, super stability, and expert steering and handling. The automatic transmission responds well and with only a brief delay. The carefully controlled, absorbent suspension provides an enjoyable ride.Visibility is impaired when the top is up, but conversations are easy with the top down. Firm, snug-fitting seats feel like they’re custom-made. Front space is ample, even though the car is rather narrow. Each CLK model has a solid, tight feel, with little sense of heaviness. The powered seat belt extension arm is helpful, but it has a tendency to snap into position.
