Good job!
IMO 8033D interior is the best of the 3. Now tempted to go catch it
after my exams le =)
I caught it on a short trip from Chinatown to Orchard Road in
it's early days back when it was a route 174 bus; the interior was
indeed much more tasteful than the production versions, which look
Stalinist in comparision.
I do hope SBS Transit considers fitting a modified version of
this interior in the upcoming fourth batch of buses; probably
taking the yellow-green colour for wheelchair slots, seats behind
the driver, and yellow plug-door poles from the production versions
but retaining virtually everything else seen on the
demonstrator.
