In most cases the difference between a woman's idea of her ideal weight and that of her boyfriend/husband is about five kilograms. Similarly, most men's ideas of what women want in a car range from the frivolous to the patronising.
One major European car maker apparently once had a concept car with remote-controlled gull wing doors to make it easier to load children - and recesses in the head restraints for ponytails. In the 1950s, Chrysler introduced the white and pink Dodge La Femme which had pink rosebuds on silver for the interior, and came with a matching handbag, raincoat and umbrella.
Most women - other than Paris Hilton and the Kardashian Klan - will be glad to hear it was a total sales flop.
On the other hand, Volvo got it more right than they could possibly have guessed when they assembled a team of highly talented women engineers in 2003 and gave them carte blanche to build the car they wanted.
The resulting concept - the YCC - was anything but a girly car and eventually went into production as the C30.
