Did you get Merc's CLK verts in the states?
The Sebring got a case of the uglies which has been getting worse and worse with every model year. My father used to have a 2002 or so model, which still looked quite nifty, but the two major revisions since are just unbearably ugly.
Now he's got an E cabrio. That's probably still outside your budget.
The camaro convertible is also supposedly a four-seater.
