I am 17 years old and living in Illinois with my parents. I have a car, but recently I have been thinking about how fuel efficient and fun a motorcycle would be. I want to present a good arguement to my parents for why I should be allowed to purchase a bike. I also have a few extra questions. What important information is needed to know, so I won't get scammed if I purchase a bike. For example, important information for a car would be that 150,000 miles is a lot on a car. Just to let, you know, I would want to purchase a sports bike. Should I or should I not get a sports bike. One of my cousins has a sports bike so why should I.
