Biggest problem that I've seen on the Supers with the 60" decks is broken transmission cases at the front attachment point caused from twisting of the frame. Take a few minute and read these.

Edit: If this is the 2084 your talking about, price is higher than I would pay for it. Doesn't look like he takes very good care of it with all of the grass on top of the deck to rot it out. Broken lift link is no big deal, pretty sure you can still buy those new. I'll check.
Edit: 2 Looks like you can still buy the link, see pic.
