My DD is an '06 Chevy Silverado, and I've "souped" it up a little bit to increase my daily driving pleasures!!
I've also put (2) 8" Subs, GPS, CD, MP3, USB player, bedliner, blah blah blah... Oh and the K&N Filter like MikeyP!!!
If I were you, I'd keep the Saturn and drive it until the wheels fell off of it. Save your money and do something with it that will get you MORE money in the long run
