I think a DS would be a great car for a teenager. My daughter will also get our DS in .......10 years. LOL! Personally, while I will pass one down and buy a new one for ourselves, I'm not one who will buy my kid a brand new car when she's old enough to drive BUT I say if you have the means then get your kid what ever you want to get them...its your money and your kid.
Around our area kids are driving all kinds of pretty nice cars.
