those spring aids do seem to raise the vehicle, they only aid when the load is too heavy, so if a car is low they will not help much.
back to the topic, if you prefer sliding doors then the mazda is for you, if you need a cheaper option in that class then the mazda is for you, the best hapa is just to visit one of those car yards and drive both cars, while at that also try the honda stream.
my opinion is stream, premacy, wish in that order, if you are watching your cash then premacy, stream, wish, if resale value is important to you then wish, premacy, stream.
