Yes, these budget versions are alot cheaper, but like Qhris said, it's all about image and the name. You'll end up being the laughing stock anyway because you couldn't afford the more expensive versions like the Q7 or the 7 series.

I'd rather have a car that I can afford than buy one with a name for show.

LOL, I remember that advert, Peugeots rock, I used to have one back in the day :-)
