What kind of pictures do you need? I can send you some interior and exterior pics of boats that I looked at and also my boat, only thing is they are all 1988-1989 300DAs. The '80s 300 DAs all have the same hull and the interior stuff is also very similar, except in '89 Searay stopped using all that Decragaurd wood look plywood and switched to white. I've never figured out how to post pictures on here so if you send me an email at QCPIPP"at"AOL.COM I will email them to you. Either that of tell me how to post pics on here.
BTW there were three basic color schemes used; Blue canvas with blue stripes, blue stripes in the seats, a blue dash, blue cabin carpet and pale blue headliner. Then there was the Green canvas, with green stripes, green seat stripes and a green dash and green cabin carpet with pale green headliner. Then there was the Red canvas, red stripes, red seat accents, red dash, red cabin carpet and mauve/pink headliner. We liked blue the best and the green second. Red was our least favorite because it didn't age well. It tended to fade to a mauve almost pink shade. My wife liked blue so we hunted till we found one she was happy with. There were a myriad of fabric colors and patterns used on cushions. Also alot of chages were made by previous owners to various boats.
The biggest difference in the cabins of the boats we looked at was the presence or absence of a built in microwave cabinet at the galley. I liked the feature as it freed up counter space. Unfortunately ours doesn't have it so I may build one someday.
You may want to go to Yacht World and search on 86 300s. Many have alot of interior pictures posted.
