This with the exception of executives taxis (usually found on luxury hotels) that were plain black and with tinted windows.
The first taxi fleet to be offered was the Fiat Premio in white with a yellow, black and blue checker sticker that would cover 1/3 of the doors in the middle.
Those units were a complete failure because taxi drivers in the country were accustomed to drive heavy duty American cars from the 1970s and early 1980s like the Chevrolet Malibu, Dodge Dart and Ford Maverick, destroying most of the units in just a couple of years.
This time the fleet was made of a better powered Fiat Tempra specially assembled for taxi duties.
Also a new fad was created, making most people feel safer driving the newer uniform cars than the old multicolor ones.
