I would have to say the 6 disc cd player is not worth it, you have a mp3 cd player so do you really need 6 mp3 cds in your car? thats 700 * 6 = 4.2gigs of music, Ill be fine with my 700mb, which equates to about 175 songs per cd. That color option is pretty nice tho, cuz the stock amber isnt very pretty, but then to make it match you would have to change all the lights including the AC screen. Well as for the most worthwhile options I would have to say any of the suspension mods will give you most enjoyment of your ride because I believe handling = fun to drive. The TRD exhaust seems way to expensive for an axle back system, and the intake isn't necessary if your thinking about the SC. So I would go with all the suspension mods, front tie struts, shocks, sway bar, and springs. The shifter & pedal would also be a nice option to do, but recommend purchasing from http://www.mcgeorgeparts.com/ bcuz they are very easy to install and cheaper thant he dealer. I never liked the feel of the stock shifter and the look of the stock pedals dont go too well after you install the shifter haha.
