i have a friend who always insisted the boxster was not a 'real' porsche; he laughed when i told him i was buying one. he came into town last year and i gave him the pleasure of a 'spirited' check ride (side note: i have some race track experience). after about 20min, we had to pull over so he could literally vomit. he now owns a boxster.
....haven't had someone say that to me in person yet.
If I were to hear that, I would just remind myself that at the end of the day, everytime I drive my PORSCHAAA... I get an instant permagrin that has only comes with driving this car!!
