The car's fuse for that plug is 12A. I have a DC-DC step-up (12v to 19V) with a max output of 6A which is needed because my solar charger requires at least 18V before it will start charging, so using the step-up will "trick" the charger into thinking a solar panel is attached. snaptube vid...

I haven't driven or checked out the car in person yet (other than a quick walk around one evening). Is there anything else I can look for to help give me an idea of whether I should walk away, or buy it? The shop isn't a Volvo specialist shop, so I'm sure they didn't check things like the PCV system...
