Age hmmm... I'd say somewhere in the 4-5 year time frame if I wanted to make an honest guess. Old enough to be not even close to warranty period if that's what you're getting at
How long was it used, couple years maybe? First motor is still going strong from what I can tell. Sorry for the vagueness of the time answers, it was long enough ago that I can't honestly remember how long it was
And it most definitely was a kit.
