I'm going to look at 1990 Four Winns 170 with the 3.0 I would
appreciate any thoughts on this boat, or things to look out for in
this make/model/year.

The dealer is asking $4950 and NADA is listed around $3500 (nada even
sounds a little low...can you really get these boats for that cheap?),
so I would also appreciate any thoughts on what this boat may acutally
be worth.

I have not seen it in person yet, but the pics indicate a well taken
care of boat.
