In a VW dealership, checking out the VW Up!

I had never seen the car up close (it has just been launched over here). There I was, crawling around the car checking out the not-so-obvious bits. Salesman standing near, I dare to fire a question:
- What kind is the rear suspension?
- It's super modern, very technical
- McPherson?
- Yes! That one, just like Formua One.
- Doesn't Formula One use Double Wishbones?
- No, that one is on the front Wheels. The McPherson is on the rear wheels.
