Before being booed by my CX-7 fellahs for browsing in the (wrong) (angel): I'm not trying to compare CX-7 to Mazda5, but if you love the Mazda3 and family is a buying factor it may be worth to also check out the Mazda5. No AWD nor DISI Turbo plus a sliding door but the 5 is based on the 3, drives great (I got a 5MT) plus covers all my family needs (space, versatility, fuel economy, no big loan, ... and wife loves the fact that it is IKEA box size compliant plus the car looks good). On top, the 08 model has now many improvements/enhancements which may be worth looking at (since 07 there is even leather and HIDs options).
OK, now I can be booed
