10k is way too much money for that machine, I would say 5k would be alot more like it, when I started my business I had a chance to buy a performer with 3500 hours for 8k, I was getting close to doing it, then I thought jeez I can have a brand new smaller machine for 11k, I went with the smaller machine and am glad I did, look at it like this, with 5k hours, it really totally depends on the maintainence, the engine is likely good for a good deal longer, because its a Nissan however the blower exhaust HX will likely soon need replacement, along with the water pump, figure check valves etc, the blower could also be getting old as well, if the machine comes from a humid climate its likely rusted to hell to boot, the main HX could need replacement soon, basically alot of expensive parts could be ready to go or soon need replacement, If I wanted the machine I would plan on buying it at such a price that replacing a few things would not be the end of the world, however this is me, I have had to keep prochems running for years, I know the machines very well, if you are not mechanically inclined I would say pass on this deal as it could be a money pit
