Well, upto 180km/h it's really easy to drive it.
After 180km/h you do notice speed a bit more.
Over 190km/h you'll usually want to stick it in 5th gear, as 6th is starting to struggle a bit.
Basically, I find 160km/h as nice cruising speed.
Btw, for guys talking about high revs, here's pic from my old Civic (no it's not photoshop.. it's just different engine - VTI, with original cluster):
.. and best part is rev-limit is around 8200rpm, so needle goes out of range a bit.. looks really cool
