If she wants space, take either the CRV or the CX5. Both are very new in the local market and will carry more "wow" factor.
Brandwise, Honda carries a little more clout than Mazda here in the Philippines.
The CRV is CBU Japan (imported directly instead of knockdown unit), and if you wait a little longer for the Thailand variants you may be able to get a little more kit and toys for the same amount or cheaper. Better ask people from Honda if they have any idea re: this.
The Forester is probably an outgoing model as the Impreza platform was replaced only recently. Baka ayaw niya ng New-Old car.
The XV is smaller inside compared to the other choices, like an Impreza on stilts. Nice "porma" car though.
Bottom line I guess, the vehicles on your current shortlist aren't bad, so whatever the wife wants - I don't think you'll be disappointed.
