Why is my Nissan Sentra not starting?

I’m thinking about buying a manual-shift car, but they’re disappearing quickly. My friend is a mechanic, and he told me that Hyundai still makes a few models with a stick. Before I test drive one or buy one, I want to make sure the clutch is covered by the warranty—will the Hyundai warranty cover a clutch?

As cars are built with more and more electrical components, I wonder what the cost of repairs is like. How much does it cost to diagnose an electrical issue in a car?

I was in an accident a few days ago where I wasn’t at fault, but I’m perfectly fine and only sustained minor damage to my car. My only issue is that the officer on the scene told me that my license was expired. He didn’t give me a ticket; he just told me to get a new one. Is my insurance invalid because of an expired license?
