you will if you wreck it
seeing as how this is going to be your first car and you're in high school it's a safe bet you have almost no real driving experience (as far as the insurance company is concerned at least) and the track record of most teens in mustangs is not good...plus the more you drive it the higher the odds are that you will hit something/get hit.
So honestly I would just get something else and wait until you have more money and a better driving record to get a classic mustang
