Building a Metal Earth Tardis is sort of like making it appear in the world, so its completion might warrant singing a certain tune, or making a certain noise...
You could probably collect enough Metal Earth spacecraft to make a timeline of our progress. It's pretty neat to see how far we've come, and imagine how much farther we have to go.
You've done it! You have finally put together the most intricate Metal Earth 3D model. A lifetime achievement worthy of display. But what could possibly properly showcase this beauty? A solar spinner, of course!
Unfortunately, this model can't bend space like the original. It can, however, be moved around in the air and nothing on it stops you from going "Pew pew!", so it's still a pretty good deal, all in all.
Cable not included, unfortunately. Can you even call it a cable car if it doesn't have the cable? I guess just calling it 'car' wouldn't be very descriptive.
For when it's too cold to go to the actual Golden Gate, because let's be honest, that would probably be less work. Or, for making models of San Fransisco to terrorize with big stuffed monsters. Really, the possibilities are endless.
