Vehicle customization wishlist

GTA 5's Los Santos Customs was great for its time but still felt restrictive. For GTA 6 I hope we get: widebody kits, stance tuning, engine swaps, interior customization, custom wraps with a livery editor, hydraulics, underglow, and performance dyno testing. Car culture in Miami is INSANE, so Rockstar needs to go all-out on vehicle customization. What mods do you want?
