I think the stock Yaris has enough power

Yes regal honestly what is the fastest car you have been in?
1liter something or another?

I come from always being in Mercedes and pretty much every other car other then a Yaris 100hp.... And I LOVE the feeling of an AMG car pushing you into your seat.

Here is one from just 3 days ago. E55 AMG, being modified with a larger TB, changing out the supercharger pulley(i know I cant spell right now, yawn), and other stuff.

Then I also get to drive my friends S600, 530HP to the wheels, and somewhere between 600-700+torque to the wheels. Its amazing honestly. Doing 60mph, wanting to go around someone, and too much gas will propel you past them at an unbelievable speed. Not something that has to be ever used, but its there!

Then when I get back in my Yaris, Its slow, no leather, but damn it does REAL GOOD on gas and thats ALL I worry about, that and it looks good either way!!!!!!!
