I'll just copy basilisk4's post and change it to my preferences (because I'm lazy):
Worth it:
- Ground Effects <--This is really worth it to me, especially if you add it in to your payment.
- Carbon Fiber B-Pillar Applique
- TRD Exhaust
- Can't forget about the floormats
NOT Worth it:
- 6-disc CD changer
- Bazooka subwoofer
- Rear Lip Spoiler (unless you just love it)
- Pedestal Spoiler (same)
- Scion Security
- Auto-Dimming Mirror
- Billet Grille
- ToyoGuard (if it exists in your area)
- TRD Shocks
- Weird expensive battery tie down thing.
- Any of the trd engine crap, i.e. radiator cap, oil filter, etc.
Toss-up (matter of personal preference):
- Scion XM <--Really expensive at the dealer (well, mine at least). I'd go for an aftermarket version.
- Interior Light Kit
- Rear Bumper Applique
- OBX Shift Knob
- pedal covers
- TRD Springs
