As long as it's just the panels that are sagging (and nothing structural) this should be easily fixable. They seem to be in good condition, simply unattached. Velcro patches strategically placed might be all you need!
As to the R32 itself, neat looking boat, very sleek and a grown up version of the Ranger 28. Personally I don't like the interfering shroud rod/chainplate mid berth, but I suppose you can learn to live with it. I do like the tumblehome look.
These boats were aimed at racer/cruisers rather than cruiser/racers (as the R29/33 were) and so are more demanding to sail, esp in a breeze downwind.
I expect you'll be getting a decent price on this one.
