Hello, I am interested in a SL 350 R 230 (from 2008) or a SL 350 R 231. I would not be averse to a SL 500 R 230 (2008-2011) either, since I assume that a V8 vacuum cleaner will surely be a lot of fun and more stable in value. What should you pay attention to in general and especially with the SL? Accident-free, checkbook care, etc. of course makes sense, dealer with warranty/guarantee sure too. Age / km-performance sold only for export / dealer? What should you pay attention to in the car specific to the R 230 / R 231? What should you take a closer look at? What should the car not have (ABC for example?)? Can you buy with a good conscience from private? Greetings & thanks
