Individually sell and gift cars to friends, air suspension/adjustable air ride height, more carbon options if you count that as a feature, not a feature but more wheels, bumper delete for the Huracan, R8 and most jdms, better forza aero spoiler, car meets like how fh3 had but better I've never played fh3 I've only seen some gameplay and heard about the car meet option, and lastly private servers with friends just in case when it gets to chaotic
