I'm looking at a used 2013 Rancher 4x4. Pics look new and owner said they barely used it and probably only put 3 tanks of gas through it. If this is the case, then it has spent a lot of time not being used which gives me a little concern since I am under the impression it isn't really good to let these sit for long periods of time. He is asking $5100. What do y'all think? Do my concerns about it sitting too long have merit, and is the price fair?
