The pricing is a bit high- but again, I found when we were buying ours in 2011 that NADA was a lot lower than the actual market.
I don't get hung up with what NADA says-- just compare to the actual market.
We bought our '98 Coachmen with 111K for $7500. It had new tires, recent 100K tune up, new shocks and other front end parts. A/C is ice cold in cab; everything in coach works as it should. I had to invest in rear brakes, brake lines and a new roof-----------I am into it for $11,500 now.
Make sure the unit you are looking at has had the 100K tune up, has good tires, (suspensions tend to need maintenance around 100K), roof is in EXCELLENT condition- preferably replaced, and everything in coach works as it should.
Don't let mileage scare you- engines last longer with less repairs when driven on regular basis.
