You'd need precisely 382,858. Oh and 22 designers spending 2,500 hours constructing it. Though If you were going to build a Lego replica of a car, wouldn't it be something a little more exciting than an Explorer? Well yes, but the reason behind this madness is a partnership between Ford and Legoland Florida for the opening of a new themepark in October.
It was actually built at Ford's Chicago Assembly Plant and weighs half the amount of the real thing. It'll be displayed in front of a Ford driving school for children at Legoland, where children drive Lego cars through city streets at a whopping speed of 3mph and earn a 'driver's license'. At least now there will be something for the dad's to enjoy for a couple of nanoseconds.
