Hello together, maybe someone can give me a few tips or make my purchase decision easier. I’m just about to add a SL R230 or R231, in any case 8 cylinders. Now to my questions, come into question SL 500, 55 AMG or 63 AMG, there are serious reasons to not buy an eg: 63 AMG? Unfortunately, most already have the facelift done what I have to take care of. Is an AMG in maintenance more expensive than a normal, if yes why? Which kilometers to go? enze would suggest you. I would be very pleased about information from you. Andi (who hopefully will drive SL soon )
