For me, well for SBS Transit, i can't really say what buses to
joyride because I haven't been exposed to alot of SBST buses.
As for SMRT, i would probably recommend these few buses, sorry if
these buses are already mentioned, because all except TIB1049L's
replies are pages way back. Amd im sorry if I sound like telling
some story, but i just want to recommend these buses.
TIB425R and TIB426M have power, and has special turbo. Both have
great aircon and they are probably a good 61 joyride.
TIB442R has power, good aircon, is very clean and still maintains
the change of gear from 0-1-2. (: But don't take the bus when the
white-haired SL is driving, he jerks the bus all the time.
TIB471G and TIB472D are speedsters of 700! Very fast buses, and
they were fast too under WLDEP.
TIB481C has that new-ish smell and runs like an airplane, the
transmission is also quite unique.
TIB515P has that AMDEP-ish sound though she is from KJDEP.
Transmission is very unique! And don't be fooled when this bus is
slow, actually she can go quite fast, depending on who's the
driver...
TIB567P has a unique pickup and bell. The brake sound has some
higher-pitched sound at the end if you listen carefully.
TIB577K has power and still maintains that AMDEP
transmission.
TIB588D, like what TIB1049L said, has a special transmission, but
also can speed and she fairs the hills quite well on 173!
TIB595H also is quite good, and has speed. Though at points the bus
may be weak.
TIB602X has freezing aircon, special turbo and also has that
constipated pickup.
TIB668G also is quite a fast scania, still remember this bus
speeding on Mandai Avenue while she was WLDEP 171. But she vibrates
violently, a true OSIM...
