Can a scion tc be fast enough for me?

Alright. I know this is an odd question but I need to know what I can do before I buy. I love the style of the Scion TC's. But when I drove one the other day it just didn't have that geez this is crazy feeling! It's very close for me but not quite there. I just want to know if there is anything I can do to one to make the acceleration a little bit more satisfying. I really don't care about top speed cause that will only get me in trouble I just love the feeling of jumping off of the line. Quickly! If there is nothing I can do please feel free to offer suggestions for cars. I like automatic, don't want to shift in the snow not that skilled with it. So any car with only manual won't work. I don't want an old car so try to keep it 07 and up. I would like to stay around 15k. I don't care about awd, fwd, rwd it doesn't matter to me. And it needs to be able to seat at least 4. I know that's a lot but I won't buy another car for 3 or so years. Thanks for any help!
