I currently have an 07 550SL with 15K miles and lately I have been craving more current technology in the later model 550's and have my eye on a 2013 with 30K miles and all the bells and whistles but of course with the later technology comes all those things that are very expensive to repair. Also moving from a naturally aspirated V8 to a twin turbo. I can't decide if I should make the move......any advice ?
