The P859K model is the base 125PS 1.6 liter Ambiente MT, it has the usual basic features like dual-airbags, ABS, 4-wheel disc brakes, power windows, power door locks, power side mirrors, global open/close window (using the key fob). Unlike the higher models, the Ambinete comes with 16 inch steel wheels with full wheel covers (but uses the same 205/60R16 tire-size as higher models).
I asked Ford Manila, back-up sensors can be added as a dealer option.
I haven't seen the actual local spec Ambiente model but based on the info, it should look similar to this.... except lefthand drive.
If you can live without alloy wheels, I think its worth considering, specially if you like its styling, solid build and good handling. If you prefer more bling though, there are also other choices out there like the 1.6 liter Lancer EX GLX for example.
