There's something extraordinarily sexy about a woman who can handle a car. Especially when they also dream that their plain-Jane-Z4 is really a BMW Z4 GT3 — just like the woman in this BMW web advert. Rowr!

The BMW Z4 GT3's a $408,000, roll-caged, carbon-fibered, 4.0-liter V8-powered, six-speed sequential shifted track-day all-star. It also comes shipped in boxes. Watch Team West Coast Racing put theirs together in this time-lapse video compressing 600 hours of labor. [ColdTrackDays]

This BMW Z4 GT3 comes fitted with the 4.0-liter V8 out of the M3. In race trim that engine sends 480 HP through a six-speed sequential gearbox. So, wait, why can't we have a Z4 M again?
