I don't recall right now what rpm my civic does at 98 but at 70 it's right about 3000 - I'd feel like I was punishing the car to drive faster for a sustained amount of time.

I drove a '90 Prelude that was at about 3400 doing 65 :chuckles: (just about redline @ 120) Never got picked up for speeding in that or my current car


edit: BTW first time I got pulled over was doing 70 in a 40 - I got off with a warning
