How much is a used 2007 Chevy Cobalt worth?

I’m borrowing my aunt’s car while mine is in the shop and want to make sure I return it with a full tank, but can’t seem to figure out how to get the fuel door open! What am I missing?

I was trying to take a look at my car battery, only to find out that I guess I don’t actually know where it is. Where’s the battery location on a Dodge Journey?

I lost my vehicle to a hurricane last year. When I filed a claim, the car insurance company totaled out my 2016 Dodge Charger. I'm looking to purchase a vehicle again, but I wanted to get some insurance quotes first. The cheapest I can find is more than double what I paid before (over $500). Why did my insurance go up so much?
