Nikon d7000 camera (not working)

Nikon d7000 for spare parts; mileage is about 18,000 frames. Something broke with the tent; Either the mirror or the curtains are sticking; so it clicks every other time; Photos come out with stripes. Selling entirely for parts; if anyone has the opportunity to repair; he will receive a practically new camera. Condition is close to ideal. The case and buttons are intact; the matrix is clean; rubber bands too. If you have any questions, write; Call me and I’ll answer with pleasure.
