What my X5 worth?

[Estroil 4.8is]

OK, I just put a bid in on our first home. I could still afford the X but since this is our first home we have pretty much nothing to fill it with. So right now I'd rather have the cash from my X and purchese a cheaper more suited truck for hauling the utility trailer, tools, etc.......................... If I sold it privately what would I be looking to get for it? Theres a run down:
