It's AWD? I would be skeptical on if that's a Plus or not. That system is pretty much always engaged which gives you worst Gas Mileage. That's what I would think if I were going between a 4WD and AWD. That and if it's AWD that means it's the 5.0 which is not a Small engine either.
However, Your idea of getting a hold of him is a good one. If Some one where to offer me that much I would say "How bout 3000" then see where they go from there. If anything I would take 2700 for it. That's just me though.
