I say no. I am 19 and even so I am not ready for a smart. Think about it, often you will be going out with friends, the gf, etc and you will need some sort of back seat. I am not saying you need to get a full-fledged 4-door family sadan, it could still be a coupe but with a back seat fit for occasional 3 or 4 people and their stuff (for short distances). Also, your local HS parking lot is not the best place to leave a car like the smart for hours on end. Of course, if your dad is willing to loan you his sedan/suv for when you need more space, then get smart.
Caution, if you order today you will probably get it in time for graduation
