For good or ill, the "XX garage" isn't quite as dirty as it sounds.
Any video of a garage where several Ferraris are having work done is going to be pretty spectacular, but this video is still one of the more impressive. It is of the XX garage at the Hockenheim Ferrari Racing Days. Several of Ferrari’s XX cars were there, including the FXX, 599XX and the 599XX EVO, a new and extremely rare example of the breed. They represent the absolute cutting edge of Ferrari’s non-F1 racing technology, and they are not street legal.
You might find it more exciting to see the cars actually on the track, but this rare glimpse behind the scenes is well worth a watch.
