Seeing Double

I was browsing through Google searches of Saturn cars and thinking in 5 more years, no one will know the name Saturn, what it is or what the yell is the logo supposed to be... I clearly see its the planet Saturn's rings, but it remains controversial if that's really it.

Point is, I passed over a picture of a 2006 Saturn Vue Red Line, and first thing that came to mind was... it looks like a Porsche.

How can a Saturn look like a Porsche Cayenne Turbo, yet the front end shares shares striking similarities on ventilation:

Although the front look the same, the rears, as many SUV's are just plain with the name and license plate indentation .
