Excitement!!

This weekend I was talking to my dad and we were just joking around because that's how my dad is and then he said "I'm going to be serious now so you need to listen to what I'm going to say." I thought he was joking but he had something serious to tell me. My dad informed me that he and my mom are going to buy me a car!! I am so excited but a little worried at the same time. I'm excited because this is gonna be awesome! I've never had a car at school before. I'm scared because I have to find it and do everything to get it but I don't know the first thing about buying a car. I need to find someone who can help me decide and go with me to look at cars and check out the engine and everything. It's so hard and frustrating and difficult I just don't know where to begin searching. If anyone has an advice, I will willingly listen to what ever you have to say. This probably doesn't convey how excited I am but I am totally stoked!
