As for me I like anything that is Volvo made.
B10M MK2: Nice engine sound, good performance, retro
design (WA PS-type)
B10M MK3: Nice engine sound, solid bodywork
B10M MK4: Unique looking(SC), nice engine sound(ZF 4HP500),
striking design(WA Strider), quiet engine sound(DM 3500)
B10M MK4 Superlong: The first and only 14.5m public bus in
Singapore
B10MA MK4: Asia's longest bus!
B10BLE: Unique design(SBS1688K), most comfortable seats(CNG)
B7RLE: Nicest looking bus in SBS fleet, unique interior
VO2X: Last NAC buses
VO3X: Superbus
B10TL VSO: Nice engine sound, comfortable seats
B9TL: Powerful, nice design(Wrights)
The only thing I didn't like about the CDGE B9TL is the loud and
noisy raidator
. Hope SBS can consider the Volvo B9Ls.
