You could actually be talking about me. I love Fords, have owned several Mustangs over the years, and enjoy them for their history and the ability to make them more personal nowdays with all the aftermarket parts available to them, but when it comes to my racing. I grew to prefer Tony stewart, my favorite driver becuase he represented the closest thing there is to old school drivers. He is not politically correct, easily gets ticked off, and can race anything, raced a few years in open wheels and Indy cars, and reminds me more of Foyt/Andretti.
So there are various reasons as to why someone pics a favored driver. My love of ponycars shoul dmake me want to pul for Roush because he builds his own line of Mustangs, but I pull for Stewart all the time!
