Always, always inspect a rental before driving off the lot.
Trunk,under the spare, glove box, under and between the seats. I’ve found empty beer bottles under the seat. For starters.
Even if they can’t get you for drinking they can get you for open container (ticket). And since you’re from out of town you’ll probably pay.
My main concern is always the possibility of illicit drug residue.
Very true. We rented a minivan to take from Oklahoma to Michigan. Happen to look deep in the console between the back seats, 3 empty beer bottles, I kid u not!
