Cheap. Also all fleet buyers in bulk.

>In Europe, most taxis are European... wonder why?

The Europeans get fleet offers for taxis... and these are special strippers.

NZ isn't Asia. Here taxis are all individually owned (not fleet), so
the buyers will generally ensure that they buy RELIABLE durable
cars... with electric everything, of course... not many stripper
taxis here.

Mercedes, Ford Sierra, Opel have all been tried... and ditched in
favor of Coronas and Camrys. Doesn't this tell you something?
