Where is the Ford Escape battery location?

I have a flat tire on my Dodge Caravan, and I’m pretty sure that the guy said I have a spare, but I don’t see it anywhere. Where do you find the spare tire on Dodge minivans?

I recently bought a used car from a family friend that is in great mechanical condition, but the interior and exterior could certainly use some work. I can clean the interior and exterior, but what’s the best way to fix a sagging bumper?

How much would it cost me to get my car lowered? I want to do it but someone told me it’s super expensive and I don’t know enough to do it myself.
