I am looking at 2013 SL with premium package with about 32K on it. Local to the Seattle, WA area and has been driven here in the PNW the whole time. I know that the advise is to get a post 3/13 manufacture. This one is a 2/13 manufacture date. Would this still be a deal killer if it was driven the whole time in the PNW. Price would be $12,500. 12 bars on battery, but waiting to get a dongle check the battery with leaf spy.
