I really hope that your parents do not regret that choice, but its your choice to make sure they never do. We have been there and it is such a terrible adversity to have to deal with. I want go into the details but please drive safe, don't push it , one mistake with a car like this and it could be your last, not to mention how it changes life for everyone around you.
You must be very mature for your parents to have this much trust in you. Prove this to be true for them. Always buckle up, drive safe and when the peer pressure gets to you, stop and let THEM OUT!!!
