I don't think it has anything to do with people driving a X5.

Here is another quote about a Jetta being a chicks car

Ray: Anyway, here are the top five chick cars, according to people who visit the Car Talk section of www.cars.com, along with selected comments from the nominators: 5. Dodge Neon -- "Neons are Barbie cars: little and cute and rounded in the hips. Even in black, they are feminine and adorable, only just a bit tougher, like Tattoo Barbie." 4. VW Jetta -- "Anything by Volkswagen is a chick car. VW realized this years ago and joined forces with another company to sell guy cars -- they called that company Porsche." 3. Mazda Miata -- "I discovered this phenomenon when I got a Miata. `Girlie car.' That's all I heard." 2. VW Cabriolet -- "All teen-age girls classify them as cute. 'Nuff said." 1. VW New Beetle -- "A chick car, definitely. And made to be so. How? I know of no other automobile with a FLOWER VASE as standard equipment."
