The Soviet space shuttle Buran launched and landed (unmanned, because it could) once very successfully. I would think it would be a very valuable industrial asset for the bankrupt Russian Republic that came just after Buran's success. But it never flew again.
Were there decisive technical issues with refurbishing it for a second flight? Aside from the political and economic obstacles. Since it didn't carry its main engines, I'd think it would be by design easier to reuse than the STS shuttle orbiter.
