Not bad price for a 4x4 F250, yea 6 cly is dependable and torquey, just not much in the way of top end.

Seat sounds like a swap in, does it have a fold out arm rest by chance?

Insp the front cab mounts for rust and ck the steering box for excessive play. Make sure the transfer case/4x4 works also.

If it is stock and no lift and big tires it should be in good shape mechanical shape.

Oh yea forgot to mention the push bar is worth $$$$
