Will my car insurance go up if i buy a new car?

How much cash could A - 16 yearold must buy yearly insurance over a sportscar? Like a 1999 ford mustang
"I requoted myself online with AAA"I am 17 and i have a fiat bravo 1.4 2008. I hear some manufactured choice to be named as being a driver and that  insurance  at my era is extremely substantial. My dilemma is i stay with my mother if she named me as a second driver although she doesn't have no licence and can or not it's feasible. Or even how to get another alternative of getting  insurance
