just a random observation/question: does anyone know why there aren't any Wigo taxis?

yung pinakacommon is ofc the vios, but i've seen dzires, accents, mirage g4's, innovas, avanzas, hell even hiaces, crosswinds, & monteros be used as taxis in PH. but i'm just curious as to why the cheapest model out of them all, a humble little MT Wigo, isn't being used for service? it already comes in white variant, and this model is seen used in other countries like Vietnam as a taxi, so why not here?

i figured for how much cheaper it is to buy and maintain, esp w rising gas prices, the wigo would be operators' default model choice for their fleet. could anyone in-the-know shed some light on the matter?
