As for me, my favourite bus model is obviously the:
Mercedes Hispano. (The 2nd batch of bendys after the
405Gs).In particular, TIB 977 P. It has a unique engine like that
of a 0405, different from the normal ZF gearbox type on the
Habits.
MB 405G, in particular TIB 877 U. Reason is same as
the above.
