The Sebring Convertible lives in a world of threes: three trim levels, three different kinds of tops, three interior themes and three different engines. All Sebring convertibles are built alongside the sedan and share a reinforced version of that car’s structure to reduce cowl shake, the annoying body quivers many convertibles suffer when going over bumps. Vinyl tops are standard on the base and Touring models; Limiteds get a cloth top. Touring models can opt for cloth, and like the Limiteds can also get the hard top. The base model’s 2.4-liter four cylinder and the Touring’s 2.7-liter V6 come with a four-speed automatic transmission, while the 3.5-liter V6 in the Limited has a six-speed automatic with Chrysler’s AutoStick manual shift feature.
