Aygo, Prius and iQ rated best for running costs in Auto Express reader's poll

Not only did Toyota achieve a clean sweep of the top three positions, the second generation Prius rounded off the top five to set the seal on an emphatic success.

The results were based on the opinions of 29,000 motorists who took part in this year’s research.

Jon Williams, managing director Toyota GB, said: “There can be no better judges of the day-to-day value of driving a Toyota than the drivers themselves and these results demonstrate how our commitment to quality in every aspect of the cars we make and sell is delivering real benefits in terms of how much it costs our customers to run and maintain their vehicles.”
