LOL! Sometimes it may not be the wife's preference. Sometimes the man also have his own sentimental ones. For example, buying cars. Some people are diehard Benz type. Why? Not because they have compared all the specs and costs etc, but maybe because their family car used to be Benz, so legacy thinking rules. Or maybe they just like the logo! It's buying what they like, not what is right. People are strange people lah! LOL!
