Bruh... you mentioned crazy rare bus manufacturers from central asia and the balkan region but you didn't include the south american Metalpar, El Detalle, Metalsur, Inrecar, LR Bus, Encava....
Nice collection, but I miss VDL. The latvian from 2004 at 11:00 is actually the VDL (Berkhof) Ambassador 200. Production started from 2001 in the Netherlands for this model. The name VDL first appeared around 1998.
You forgot 3 Vietnamese bus manufacturers: - THACO (very popular here in Vietnam, started manufacturing buses in 2011) - SAMCO (started manufacturing buses in 2006 or so) - Kim Long Motors (manufactured buses for a few months now)
