I've never seen the SUVs for sale, but I'm guessing they will either revamp the vehicle system or a modder will.
I really hope they do some work on the clothing in this game. It's too hard to give your character a consistent look without, as one website put it, "looking like an EDM kid on the last day of Burning Man".
I think you should be able to have a crafting perk to add mod slots to clothing you like instead of hoping for a better version. I also hate being forced to wear a hat/helmet to get full armor stats. They should at least do like some other games and let you make your helmet invisible. My V is running around with a completely out of place Legendary combat helmet, that I think would give you odd looks going into some of the places he's going!
I also noticed that clothing vendors aren't seeming to restock any more (Level 40). The mods they offer are updating, but the clothes are the same even if I wait days.
