What's up! Just traded in my 2010 G37 for a 2015 WK2 Limited 4x4 (lux II package). Needed something with more space. I'm definitely not driving a sports car anymore, but so far I am loving it! First small project is getting the windows tinted and replacing all interior lights with LED's. Any other projects/upgrades you guys recommend? I want to upgrade the sound system, but after some searching that seems like too much of a hassle/money pit.
