if you can afford it and are responsible, then im happy you got it. i got my 2010 ss when i turned 16 right on my birthday. Never got one speeding ticket, or into any accidents. im 17 now and still loving my car. dont listen to people when they say a 17 year old cant handle a 550 hp car. it all depends on you. ive driven ferraris at the age of 17. hope you enjoy your zl1. its one hell of a car. just be safe man and have fun
