I just watched that video last night before seeing this thread. If you're on a budget and looking for something fun to drive, the Fiesta ST works. And he's right about fixing a BMW when it breaks -- not inexpensive.
But this is like my dad's saying about drinking Scotch. They come in two kinds: journey, and destination. When you're home from work and tired and just want a drink to soothe the nerves, you get the destination Scotch that fills an immediate goal (e.g. The Fiesta ST). The other type is the Scotch you drink with time on your hands and you want to savor the experience for all the subtleties and nuances. It isn't just a means to end, it is an adventure unto it its own (e.g. The M3).
In the end you have to know what you want out of the car. If it isn't a comprehensive experience, hey...maybe the Fiesta works.
