First mods I plan on doing are:
LED Intertior Lighting (already purchased on ebay last night) ~$19
Infiniti OEM Windshield Sunshade (also purchased on ebay) ~$41
Running Boards (have not purchased yet)
As for the running boards, I hope to find info on this forum about whether I can install aftermarket running boards and have it not affect the sensors. I have all the sensors available to this car.
