Ya exactly. Last time took a B9TL a i find that the bodywork is
too simple. Look at the sealing of the windows and joints and you
will get what i mean.
Metal? Try the Hispano OAC/CAC merc. The sidewalls are metal, made
of aluminium i think? Air-con duct also metal, only opening
plastic. Infact, i think Hispano uses very little plastics leh. So
maybe you maybe want the Habit bodywork? 
Hmm.....cloth or rather fabric as VogelSitze calls them, are better
at "gripping". There are more friction as compared with vinyl
covering. Try the MRT seats(oso plastic mah). When the train brakes
and you are wearing polyester made clothing, you will slide on the
seats. 
The fabric seats
i dont have such problems leh.
Softness is maybe due to the hard sponge that Vogelsitze uses, the
first batch of Habits the seats are rather soft, until the 2nd
batch comes along. Also, the production plants of the B9TL seats
and the Habit's are different. B9TL's is from Malaysia , the
Habit's are from Spain, since the Habits are directly imported from
Spain right? So maybe the sponge used is slightly different i
think.
