If reliability is a major factor in your choice of car then a Honda or BMW should be at the top of your shopping list. The FN50 report, a study involving more than 800,000 vehicles conducted by Fleet News and Grant Thornton, concluded that the two carmakers supply the most reliable vehicles. Honda's Civic was named as the most reliable car on the market, while the Japanese automaker's Jazz finished third and its Accord fourth in the survey.
