Different people utilize different information. I think some women (like men) prefer the way the car looks. Is it a sporty looking car? Is it cool? Others really like reliable, point-a-to-point-b transportation. Some people prioritize gas mileage. Some like the way the car feels, the way it handles, or how fast it goes in a straight line or around corners. Some like people-carriers, like SUVs and minivans, vehicles that can haul 6-8 people and all of their stuff.
I am not a lady, no where near one. I don't know what ladies choose, but I know that I like to go with reliability, gas mileage, and good handling above all.
