If it helps I sold a 2003 SL500 about 14 months ago, it had done approx 70k miles, everything worked, but the paint was less that perfect. I got £6k privately. I think yours being the lesser engine but newer, less mileage and better condition would fetch £6500 privately. Don't try a dealer of WBAC etc, they'll low ball you. The problem with those is that they can generate a lot of diagnostics if you let the batteries get low from non use and people often think they are worse problems that they are but a full charge and clear with OBD software will fix most of it.
