Well, all that I could say is that the Mercs 0405 are ok with
me, except for the ever sickening Volvo B10TL. The bus is so slow
that almost one from each service plying TPE passed it. Took about
30 minutes to reach from Sengkang Flyover to Woodlands Interchange.
The new B9TLs can tahan at 22 minutes, the Volvo B10M clocked in at
23 minutes, the Volvo Olympians are so-so at 20 minutes and Mark
IIs can tahan at 19-23 minutes. I mean, the B10TL here are more
slower than those in Hong Kong. They have different gearbox and
power is also different.
For the Volvo B10M Mark IIIs, i think can tahan, but must improve
in it's bus lighting. The interior seemed dark to me. Mark II have
better interior lighting than Mark III. The best interior lighting
are of course, the B9TLs.
BCs like B9TL because of it's roar in 2nd Gear. The bus have a
comfy first gear and then into 2nd, got the roar of the powerful
engine. 
The Voith B9TLs don't have the roar feeling
and female BCs prefered them.
Scania is indeed the worst bus except for N113CRB NACs and CACs.
OACs always make my head go around in circles. The NAC at least you
have strong wind to ease the headache the shaky engine makes. I
must confess that Scania N113CRBs sound more simillar to the
DAFs.
Most Mercs are ok except for SMRT's Bendys and some 0405 OACs. Some
bendys have this stink at the trailer cab. It smelt like somebody
passmotion there. The 0405 OACs gives me a headache as the aircon
is stuffy and the seats are dusty. The suspension is so-so.
The SMRT Hinos are the worst in the suspension department. The
suspension is too stiff and the bus rattles the most while going
over bumps. If you take it through a hump, trust me that someone's
going to have a heart attack.
