why would top speed be important? plan on going 140mph or so everyday?
No not everyday - I'm a careful speeder.
I typically don't go over 85 mph with my current Civic unless no one else is on the road. I do set my cruise control at just under 80 mph.
If on rare occasion I do speed up beyond 90 or so I never do so near other cars or opposing traffic. I always slow down below 80 when opposing cars approach on a 2 lane hwy or when I pass etc.
Anyhow doesn't hurt to be informed as to what the 2006 & 2007 Si Civic will do or is capable of. I've searched on the internet to try to get answers but with limited results. I think I need to hit the newsstands or search for back issues etc.
