The vast model lineup from Mercedes-Benz ensures that one of its cars will suit just about anyone's needs, but the 2008 Mercedes-Benz CLK550 Cabriolet fits a very narrow niche. The CLK550 is a coupe, offered as a convertible or hardtop. With the convertible version, which we reviewed, trunk room is so limited that a couple would need to use the back seats for luggage during a weekend getaway. Four people can fit in relative comfort, but forget bringing anything else. The car is fast and handles well, but its bland looks won't appeal to most sport drivers. It would make a very comfortable commute car, but the weekly gas bill would be on the high side.
