Yes, the truth is that they are incredible machines, with a quality of manufacturing to highlight... Those who have visited these spacecrafts in Baikonur, the so-called "explorers of the Buran", sometimes highlight that the interior of them looks "as if recently left the factory", even though they have been heavily vandalized. But they can still be rescued. Some time ago, Dmitry Rogozin, when he was the Head of Roscosmos, mentioned that it is the Russian Federation's intention to one day return these spacecrafts to Russia. The issue is complicated, because as I understand it, the Buran of Baikonur are owned by a businessman from Kazakhstan. Greetings!
