seriously I think you are one of maybe ten car girls I've ever talked to in my life, and it's been my experience that they are kinda freaky in a good way and usually pretty good looking.
AS for the OP
I personally would not call the GT the best car ever no matter how you tune it. (also Clarkson sold his GT for a Gallardo Spyder)
I'm not sure what I would consider the best car, there are to many factors and you can't get one car to do it all. If yo can please tell me because I have yet to find a sweet track car that stirs the soul, can be Daily driven, can tow things like boats bikes and trailers, and is comfortable for long trips.
Yeah I'm a huger car guy too. I think for me cars might be right on level with skiing and my new thing of learning to wakeboard is quickly getting up there too, cuz I can finally rekindle my never ending love of the water and of boats.
Also Hennessey as much as I love his insane cars, is a huge crook, look it up
and the reason the Veyron is so much more is because when your going 258MPH (being the second fastest road legal car now thanks to the SSC Aero) it feels like you are cruising at a regular speed, or so TOP Gear says, I haven't even seen a Veyron in real life let alone ridden in one.
