"We have now scientifically proven the physical attraction people feel when it comes to cars."<p>Funny how you did that with no controlled subjects. Have groups that only listen to white noise, random chatter from a busy restaurant, maybe the rumble of a subway train. Even groups who listen to nothing at all, and just sit idle for a few minutes.<p>Also, I buy that sexual arousal increases testosterone levels, which would mean high levels of testosterone are <i>correlated</i> with sexual arousal. But I don't know if raised levels of testosterone <i>necessarily</i> indicates sexual arousal.
A little story, some what on topic about fast/expensive cars.<p>A developer friend of mine, who is much younger and less 'attached' recently bought a new 2008 Subaru Impreza WRX STI. Fantastically fast, pretty expensive compared to most mainstream cars and sure to get attention wherever he drove.<p>However, his first girlfriend post car purchase didn't even have a clue what a WRX or STI even was when asked and therefore wasn't impressed at all with his ride. He was <i>slightly</i> disappointed.<p>The lesson here is to buy something that is shiny, flashy and sure to attract females (think Mercedes, BMW, Porsche), not an understated best bang-for-your-buck pocket rocket like the STI.
> <i>David Moxon subjected 40 men and women to the sounds of a Maserati, Lamborghini and Ferrari, then measured the amount of testosterone in their saliva. He found everyone had higher levels of the stuff</i><p>Then why not making cheap electric cars that make exactly the same sound? I mean, just attach a stereo wired to a embedded chip that makes the length of the sound wave depending on the speed of the car.
You know what turns my wife on about our 14-year-old Honda with 170K miles, a badly eroded paint job, and doors that creak like the screams of the dying? When it starts on the first try.
