True that. I think the CGA-bound services are the clearest
examples of the preferential treatment. Either AMDEP (Sv 24 &
53) or HG (Sv 27 & 34), you look at the KUBs & Citaros perm
on those services, you will notice that they have a higher tendency
on average to appear with polished rims. That's exterior wise.
Engine-wise, for some like Sv 24, the KUBs yes some have chaotah
rims, but if you board them, they sound horrendous (like the
driveshaft grinding or something of that kind), but heck, they
accelerate way faster than the other non-CGA bound KUBs even with
that weird noise. Even with kickdown / slip-gear (I forgot what's
the exact term you call for KUBs when BC floor all the way for the
turbo to spool), the non-CGA perms have slightly worse
acceleration. Try taking a Sv 24 perm & a KUB cameo on Sv 24 in
the same day, you'll notice the difference.
Citaros wise, you can't tell by acceleration directly. But you;ll
notice for some of the Citaro cameos on the CGA-bound svcs, some of
the Citaro cameos seemed to have lacking turbo pressure already. No
kid. Try taking any Sv 151 Citaro on Sv 27, then compare with the
CGA perms, those few cameos turbo kick in from 2nd-3rd gear, the
acceleration like nothing much. LOL. 
BNDEP uh, idk why but they don't seem to care much about sv 36
exterior-wise. Just keep dumping ads onto the KUBs. BNDEP's way of
doing things. LOL. But those perms on Sv 36 do have better
acceleration as well. Try taking 8641Z or any of the 36 perms
recently and you'll know what I mean too.
Sorry for going slightly off-topic. Oops.
Yes CGA service buses will always be in better condition than
normal buses.
But from what i observe it isnt just between CGA service buses
and normal service buses.
Like for Svc 852, SMB190U rims are polished quite often and is
mostly shiny but for 189A and for it is always/seldom polished.
It's interior is also dirtier than 190U.
Also when both SMB109G and 133K were both perm 858 which goes to
CGA, 133K was much cleaned much more often and engine was much
better than 109G
Anyway sorry for being off-topic...
