Jurong point the shop - Kiddy Palace. $15.90 i remember.
OG chinatown /bugis i remember have, it's $11.10.
The first time i saw it i thought was some cheap knockoff,
but after buying and comparing with the Citaro pics around the web,
it's very close to the Citaros in European countries, except some
minor variation. Not to mention peeling of the 'ad' stickers. The
interior are quite close to the real ones, down to the seats and
the grab poles similar to the Hispano Habits grab poles we have
now.
The doors and engine cover can be opened, but it does not have a
wheelchair ramp. :p



Compare to the real Citaros on the road. (images from
wikipedia)...it isn't really far off at all!


It's called town bus for a reason - prevent copyright
infringment 
How i wish Kidsmate made a bendy bus version of this. The bendy
bus toy by Kidsmate looks too generic
This one, zzzzzz. I have the blue one, but the front axle broke
already. So i put it into my "scrapyard". My Scrapyard still have
another Mercedes Travego coach(Red one, front axle also broke.
