Considering buying a 13 Dodge Ram cummins 4x4. 4 door , dark grey in color. No leather. I believe it's an slt. Has only 33k miles on it. They are asking 34,900. How much should I try and ask for? Was thinking it's priced pretty fair as is. Maybe ask for 33k? It's bone stock. Also is there anything I should look for when inspecting the truck?
