mazda 5 vs. vw touran

Hello everyone, are just heavy hearts at the pondering, whether the new family carriage should become a mazda 5 or vw touran. find both quite chic and from the equipment there are probably also many parallel ones. the children’s diseases of the touran (built in 2003-2005) are now fixed, how it looks at the mazda. especially interesting to us the flexibility of the 2nd row of seats and whether the sliding doors really bring something? do they still work so easily after many months? should you otherwise pay attention to buying a mazda 5? Greetings Volkmar
