Age is catching up to my aunt, she just turned 88 in October and has decided to sell her house and move with her daughter to Colorado. She offered to sell her generator to my dad before she moves. Its a Generac 22kw natural gas, all aluminum enclosure, 35hp Mitsubishi 4 cyl, that was built in February 2010, so almost 8 years old. It has 198 hours. She offered it to my dad for $3,000. With that he would get the unit, the custom built stand it sits on, and all the boxes and electrical panels to hook it up to the house, hed just have to plumb the natural gas. Its in excellent shape, and runs great. Its one that turns on automatically in the event of a power loss. So, with the low hours on the unit and the price, is this a good buy? I talked to Generac and parts are still readily available.
