1992 Stratos 285 Allpro Silverstar? HELP!

I am looking to purchase my first boat. I found a 1992 Stratos Allpro Silverstar with a Johnson 150 for $5000. I've been tournament fishing as a co for a while now and need my own ride. Anyone have any knowledge of this boat? The boat looks great for its age. Is this a good buy? Besides compression tests what else do I need to be looking for so I do not make a $5000 mistake? I know used boats are a risk but I can't buy a new one. Any help is greatly appreciated. Thanks. Pics are attached.
