I agree Bird. We bought our MF 1523/snowblower as a package with 62 hours on it. Did not bother us that it was a rental unit, a local golf course used it to blow the driveway to their office, so not abused, since it was 9 months old when we bought it. Came at a nice price, with full warranty, and the 50 hour service was performed by the dealer, at no cost to us.
Sounds like you got a great deal. But now lets ask the question; How would you feel if you had agreed to purchase a "New" MF1523, paid a "New Tractor" price and the dealer delivered the unit you have?
