dont worry bout the warrenty, you'll start modding and it will be gone.

about the EVO vs. STi thing I looked at it kinda like Ippatsu Man;
the EVO - better handling and a little less power
the STi - has more power but the handling is nowhere near Evo godlyness

So, i figured it like this, I can easily make the the EVO have as much power as the STi but could never make the STi handle as good as EVO.

Also, the EVO looks so much better.

If, your not really ready for such expensive cars (EVO & STI, 30k+) with alot of maintanice, then I would recomend the regular WRX. I believe the regular WRX is great if your not totally imurssed in having a race car. Its quick , has turbo allwheel drive with less maintanice the EVO & STi or the fast that the EVO & STi draw a lot more attention then my old WRX w/o a wing.
