60004 and 018 stored 2009 014 2008.I think there's a few like 60065 which haven't been refurbished but haven't been stored that long i.e 2015. I'm not sure on 004/014/018 but they appear to be some of the last of the class to be stored (could be wrong).
I think DB may get more interest if they offer to overhaul them into super 60s
