Trading my 09 impala for 92 500SL?

I currently have the opportunity to trade my 09 Chevy impala ss (5.3l v8 Ls4 engine) for the 1992 Mercedes Benz 500SL roadster. The car has maintenance records through out its life and only has 140k miles on it- the downsides are the, top convertible hydrologics are shot, cracked heater core, hard top rear glass cracked, speedometer and radio non functioning. With all that being said, is it worth the trade?
