I don't see how a clean carfax on this type of damage could be worth the out-of-pocket cost. As long as the new top is OEM and you have receipts to prove it, it won't diminish the car's value. I put convertible tops in the consumable category like tires. AFA the seatbelt fix, that type of repair is just noise and wouldn't affect resale. No more than a few warranty repairs that most cars have.
