The SL500 from MY '03 to now is an R230 chassis (yes, I realize it became the SL550 in '05). If you scroll down the forums, you will see a set of roadster forums. There is one for the R230. That forum is full of people who own the car you are considering, and there may be some who made the choice you are asking about.
