I think they prefer B9TLs more leh..IBetter if all SMRT E500s
transfer to TT and GA,Lol!
The Enviros don't seem to be in good conditions now, I don't
think its just SMRT's maintenance, but also that the Enviros may
not be easy to maintain as compared to other types of buses, or may
not be suited for year long hot, wet and humid conditions.
