I'm admittedly no expert here on the comparison of the two models or anything, that being said... I would agree with the 2005 style being the one that I would want to go with over the 2003 for several different reasons. First and as mentioned, the 2005 has the fold down rear seat that is much more practical imo than the 2003 with the molded in rear seat. The molded in rear seat on the 2003 takes up a bunch of space that could be used as a cooler and/or to where you can put the fish that you catch. I have briefly considered upgrading from a 228 Seafarer to a 232 Gulfstream, but if I were, it would be a 2006 and newer style that's similar to the 2005+ 282 Sailfish style. As the 2005 and previous 232 Gulfstream's have a molded in rear seat and imo is just simply a waste of space. In regard to the cabin on the boats in question, the biggest difference that I can see would be the things you mentioned about the countertops, etc... but on top of that, the 2005+ models seem to have a much bigger bathroom. Or at least that's what the pictures make it seem like, compared to the 2003 where it looks considerably smaller. If it's going to be a family boat, I'm sure the females in the family would very much like the larger size of bathroom compared to a smaller one. If all things are equal, or close to them in terms of pricing, I'd definitely go with the newer version as compared to the older one. Again, I have no real world experience with either model, just going off the pictures like you are. Good luck either way and happy hunting.
