One of the 11 Ikarus 284 buses. Only 3 of them exist, but only 1 (MZE-284) is used for nostalgic purposes. BPY-149 would be great as donor parts for BPY-150 (or vice versa) if Volanbusz will have some willpower to restaurate at least one of them. This bus stands over the yard since 2007!!! Only one 284 remained AND still working and this is worrying!!
