No.
Deal separate, lease return matters much less.
Why would they care lol.
For 12 months afterwards, keep a copy of registration and insurance.
You again, have 12 months. I don’t have a crystal ball, I god damn wish I did.
Edit: Damn @DG-X5 beat me to the punch while I was watching Peninsula (Awesome movie, we need to revive the what to watch thread), but all of his info is indeed correct. Give this cursory guide a read, you’re in illinois you might want to look into owner’s choice as a better method to leasing.
