My main mods are:

1. Sylvania Silverstar Headlights
2. Nissan Rubber Floor Mats
3. Nissan Seat Covers (Front and Back)
4. Exterrior Cargo Basket Net
5. Interior Cargo Net
6. Mini X-Net
7. Rear Wiper Delay (Thanks ElectroKen)
8. Yakama Roof Bike Rack (Thanks xcanuk)

Soon:
-Superwhite Fogs/Parking Bulbs (I'm unsure about changing them so I've held off)
-Seat Back Organizer (within the week)
-Cargo Area Protector for Subwoofer (when they finally make it)

Edit: MY Mall Cruiser is better than both of yours!
