My Neighbors have a 6x10 trailer that I borrow from time to time.. I would say on a scale of 1 to ten, it is about 5-6. It could use a new deck and I put new lights on it. They dont use it and it hasnt been plated since 2011. What would be a fair price to offer them? I have seen really nice looking ones on CL for 650 or so. It also needs new tires... has 14 or 15" rims... any thoughts?
