The positives I can truly say are, the maintenance of the motor, by all accounts, appears very sound. Filters, belts, batteries, hoses, connections...everything visible has been touched, replaced, and is current. Another plus is the floor, bolts, ceiling screws...no rust anywhere...bus appears to be very solid. Air system holds indefinitely, so no leaks and literally everything functions as it should. Overall...the bus seems to be as well kept as can be expected by a large, active school district. The odometer functioned properly on the trip back, so I have no reason to believe it isn't accurate, but the hobbs well...who knows when that quit.
Interestingly, the CAT is the 330hp engine, which by all I've seen was only in the fire equipment and rv's. I expected it to have the 250 engine but, low and behold the valve cover stamp says otherwise. Someone earlier said the black headlight surrounds indicated some premium features in some ways...I suppose when purchasing the bus with the belly storage, they also opted for the higher output engine for the expected weight on board. I suppose that's a plus also.
