Why is my 2013 Hyundai Sonata's brake light not working?

Our daughter’s heading to college in the snowy Northeast this fall and we’re looking for a solid used car to send her off in—we told her she’s a grown-up now and can drive herself up to school. The Ford Focus caught our eye—but is it all-wheel drive?

My car suddenly got a lot louder after I hit a pothole. I looked underneath and the muffler looks fine. My cousin said it could be the exhaust manifold. What does an exhaust manifold leak sound like?

Do I have to get the insurance that the dealer wants me to? I purchased a vehicle from a dealership, and now they're demanding that I change my car insurance coverage. I've already signed the loan and all other papers and drove the car off the lot.
