Actually the Skoda of today is an half decent motor, eversince Volkswagen got hold of it a few years back, threw out the old engines, and totally restyled the whole range.
a lot of the taxi operators now run the the Skoda Octavia, which is both reliable and roomy, and in the case of the 1.9 diesel returns over 50mpg.
the interior is a bit on the 'plasticky' side, but perhaps this is a feature sought after by the taxi fraternity, whereby, they can now merely swill out those barf-ups instead previously having to shampoo and dry.
