Tell you what.
I know some of you do not wish to take these buses.
You can do an observational study, and collate buses that are good,
bad, average, so on and so forth. Then from there, you then can
tell whether a bus is likely to be good, bad or average.
For example if all but 1 complain about SBS 3660 B, you should know
what it means. 
But if only 1 out of 50 complain about SBS 330 Z, question the
reliability of that person.
NEVER ever use flames as part of the observational study.
You are smart people, that's why you all flame. Wrong use of
brain.
