How to fix a stuck hood on a 2002 Honda Civic?

My uncle went on a business trip and left his car at my house. I forgot to start the car for a few weeks and now the car is no longer starting. So, I tried to open the hood and jump-start the car. However, when I pulled on the hood opener on the driver's side, the hood seemed to be jammed. I need to find a way to get the hood open. If my uncle comes back and finds out that his car isn't working, i'm screwed. So, what should I do?

Would you trade a 2014 car for a 2007 car straight up?

I own a 2014 Honda Civic but it's too cramped and too underpowered for me. I want to trade it for a larger car with more room a 2007 Honda Element instead. Both have around 100,000 miles. After taxes and DMV fees, the Element would cost about the same as what I would get on the Civic.

So do you think this is a fair trade?

Car is making a rumbling sound?

Recently when I brake my car makes a loud rumbling sound that sounds like it's coming from the back. The brake pads were replaced two months ago and though this car is a daily driver it's not used excessively. Mostly to university, the gym, and back. Errands in between of course but only around town. I'm also hearing the rumbling when I park. My car can be parked for 20 minutes and you will hear it rumbling. My driveway is sloped so it almost made me wonder if the brakes are struggling to hold it. It's a 2003 Honda Civic everything's up to date. Does anyone have any idea what this could be?

I'm 14 years old and I have $1000 of my own money to get a 98 Honda Civic from a private dealer. Is there an age limit to buy a car?

Answer As soon as possible.

Added (1). I know how to talk down the price too, though that'd be beside the point -- I'm going to use this car as a project vehicle until I'm legally allowed to drive.

Added (2). To clarify, yes my parents will accompany me at a private owner.

Added (3). Or, would I be able to purchase a car from a private owner without a parent accompanying me?

Added (4). I know I can't legally drive it, however I plan on putting this time to rebuild some of the parts that need to be worked on, that way by the time I'm 16 I don't have to deal with replacing parts.
