Are Americans willing to buy small cars?

I've noticed the increase in smaller-European style cars in the U.S., and I was wondering if Americans are accepting of them. I personally would prefer a smaller car because of the superb gas mileage and parking abilities. With a small car, I can fit into parking spaces that typical trucks, suvs, vans, and certain sedans can't fit into. I own two cars, a Volvo C30 (my wife's) & a Mazda3 (mine). I have two kids and as a family, we fit perfectly fine in the Mazda 3. I always hear people saying how much they need a Van or SUV because of their kids. You could easily fit 4 people comfortably in a Mazda3, and STILL fit all you need for everyday activities in the trunk. Anyways, I don't know what the big hang up is about small cars. In the near future, I'm considering buying a Mazda2 and giving my daughter my 2003 Mazda3. If Europe, South America, Asia, & Australia can do it, why can't we?
