What's The Most Useful Car Ever Made?

Useful means something different to everyone. Some see useful as practical, others see it as fast. Others see it as a combination of everything. What's the most useful of them all?

What we're looking for here is a car that can anything you throw at it. Can it carry a dog? Can it drift? Can it baby? Can it carry a Christmas tree and your aunt at the same time?

What car fits your personal definition of most useful?
