Benq

Seen in Bucharest 2013

There is also a SERM tag on the left side. I just say it because there is a really nice video with an ERPS, SERM wholecar. 

You can also see Benq and SERM in one of the 1UP videos where they are coloring some metros together with One United Power from Berlin. - Graffiti connects!

Have fun while watching!
