Should I rent a car in Boston?

The bulb in the passenger-side headlight of my 2013 Hyundai Elantra recently burnt out, and I don’t have the time to bring it by the shop. I’m scared I’ll get ticketed driving around with it out—is it easy to change a Hyundai headlight at home?

There was a massive snowstorm recently and, long story short, I slid and scraped my car’s side against a giant pile of snow and ice. It left some scratches in my paint, and while it’s not hurting my car right now, I would like to repair this. How much will it cost to fix scrapes on my car?

A friend of mine told me that she recently had her transmission fluid changed, and it got me thinking about how I’ve never done that. When should the transmission fluid be changed on a Toyota Corolla?
