What Should I get?

Ok, in the summer I will be working and selling my current car(http://www.hondastyle.com/forums/sho...&threadid=2287), plus my dad will be adding some money.
So in total I will have about 10-12 thousand canadian dollars.
I'm wondering what I should get and what I could get for that kind of money.

I was hoping that my dad will add another 5 so I get get an SIR, but that's a maybe. SI is in my price range for sure though, but you see I don't have too much money to add aftermarket products too it, plus my dad still thinks I drive carefully lol. That's why I want a somewhat fast car that's stock. So what would you suggest I get. By the way, I can get something a bit cheaper and put in ~1-2k into products that won't be really seen by my parents (I should say dad, mom has no clue about cars). Well any suggestions welcome!
