Well you see they do it to reduce the wieght on the earths surface, therefore prolonging their existance on earth, or so they "think". 


I have owned a GM vehicle ever since I bought my first Chevy when I was 18. My wife on the other hand had a Nissan and wanted a newer one when the 05 Altimas came out in 04. That's the only reason I own a Nissan. If it were solely my choice, she would be driving a Grand Prix GTP or else a Pontiac G8.![]()
