As with everything out there, good service and parts availability, next is what you can do with it, then comfort with the machine, personally I like the fact that my Cat dealer can be reached with 1 phone call and my parts will typically be delivered next day, the service department is more than helpful with questions and in over 15 years I have received only 1 incorrect part, a hydraulic hose cut about an inch to short. Skid steer, definitely track drive, here kitty kitty!!!
