There are many good things you could say about the Porsche Panamera. It's widely regarded as one of the best-driving four-doors on the market, and with powertrain options ranging all the way up to 670 horsepower, it's no slouch.

But while Porsche has made the latest version easier to swallow, visually speaking, it's hardly the best-looking design out there. It's relatively understated, though, in Zuffenhausen's signature style. But Mansory has thrown that right out the window with the model it's brought to Geneva this year.
