We just bought the Mazda5 Touring 2012 and researched this car quite a bit.
We did not really want a true minivan however this car was more like a larger economy car with minivan features.
So far so good.
The best features are the rear sliding doors.
It makes it easier for our son to get in and out.
The look of the Mazda5 is great and doesn't look like a full sized minivan.
Suggested improvement would be to offer this with privacy glass as standard. Also incorporate the roof rack system with the car and make the cross rails the add on accessory.
