So, I guess it's part of the cost of learning (first time owner): the pre-buy report I got mentioned a few "squaks" that were noted as $200-$500 fixes (minor hangar rash on aileron trailing edged, and a minor fuel seepage).
However when running the annual now, these two items are basically airworthiness issues, and can't just be fixed with $200-$500 (control surfaces can't be fixed or stop-drilled - need either reskinning, or replacing, fuel seepage isn't something you can seal from the outside and monitor - need to drain tanks, get in there and properly seal).
What's the responsibility of the A&P who performed the pre-buy? Should I be going to them to cover the cost of fixes since these are airworthiness items that should have been noted as such in the pre-buy? Just suck it up and check it off as the cost of learning airplane ownership?
