Negotiating Price

The really good ones sell quickly. Might not have too much time to negotiate.

If your looking at private sellers they maybe upside down on the MH and trying to walk away free and clear.
Dealers that take trade ins on new sales genarally only give wholesale value to the buyer but with the huge MSRP's on new MH's can fudge the value of the trade to let the buyer think he's getting a better value on his trade. And once the dealer has that trade in on the lot he wants to get rid of it as soon as he can because that's where most of his profit is tied up.

If the coach was someones baby then it may be worth more.

You want to get a good buy purchasing an RV you need to first determine what a "good buy" is for your particular rig ... and then be prepared to walk away when the you/seller disagree. It's not matter of a std discount from listing price. Well maintained rigs are worth more regardless of NADA

And to confuse it even more they will then add transportation cost, Dealer prep, Documentation, PDI and other "fees" to the deal. Totally confusing what the rig cost, and that is their plan.
Myfirst suggestion is to shop for a dealer. some (mostly small mom and pop locations) will give you a straight up, out the door price. Research those, and use their numbers as starting points, you know they still have some breathing room in their numbers, so shoot for 10-15% below those prices. If the local dealer your looking at doesnt price that way, ask what their "fees" are and for a list of them, add that to whatever price they are giving you and go from there.

they have a SC location that may help and they do price things "out the door".
