That post was actually meant to be sarcastic. Guess it wasn't so obvious, I should've added emoticons.
I cruise at 145km/hr as much as possible. I'm used to much higher speeds coming from Europe, the 100km/hr is a toddler limit on the highways here. I'd go faster if they didn't threaten to take my car at 50 over.
I do 50% city, 50% highway, I get about 650km per tank on my 4-auto 2004 Mazda3 2.0L. I'm excited for my sky, the 2 extra gears should help!
