Unknown condition might be a bit more accurate. Don't know if $13.5k is your number or what the seller is asking, but it's well off the typical asking price for that model. If it's the asking price, it suggests the seller is acknowledging the unit has some kind of "history". The loader hydraulics shouldn't be leaking after only 300 hours, so what was done to/with the machine to cause it to leak early, and what else is going on you haven't noticed yet? Same thing for the instrument panel that shouldn't have failed or been damaged in ordinary use so soon. You may have a bargain here, but it's a "pig in a poke". I'd keep looking.
