Found an early Case 310 dozer for sale that I"m kind of interested in. Owner says it hasn"t ran in a few years, so it should need a basic tune up to get running. It"s a gas engine. He says the undercarriage isn"t perfect, but it"s pretty good for its age. He"s asking $1700 for it. Does that sound like a good price for it? It doesn"t look too bad from the picture, but I haven"t gone to look at it in person yet. Any input would be appreciated.
