I'm about to put an offer down on a 2008 Lund Explorer SS with a 115 HP Mercury 4 str. Basic boat, motor and trailer, with no options, no electronics, no trolling motor. I'll add those later but I'm at a loss as to what would be a reasonable offer. It's a nice boat with a lot of features standard on the boat. Any help would be appreciated. I'm new to the boat world and there's lots of variation here in the market.
