Sounds like you're a little too into the Yaris already.
I do get what you mean though.
I know my Type R is supposed to be a "fast car" but compared to my old Zed it's so sedate I feel like it's a 1 litre. Been watching my MPG and everything.
Don't worry, I'm not becoming civilised lol.
I found when I had my VTI that it egged me on to rev and thrash it, so you're doing well to fight that urge lol. But then at the time it was the most powerful car I'd owned at 170 bhp so I'd probably do the same as you now even if I had a type R, having already owned a TZed.
You feel like it's a 1 litre? Well mine IS a 1 litre lol.
We should race. (not on a public road though obviously)
No not on a public road, Don't want my yaris to spin out in 3rd when I floor it
...... And then you'll get smack down from ekona
