SL 350 buy? Experiences wanted!

Moin, am I just thinking about buying a SL 350 year of construction juni 2004. He has only a few kilometers. Drive currently as a second car a CLK 320 year 07/2002. He has no problems and I am also very satisfied. Is the SL 350 so sporty? Does it have a good quality? What else do you have to consider. Should I wait until other young used ones come to the market? Thank you Gedeon
