My 1.9 cruises quite happily at 105mph at 3800 rpm in 6th gear (though of course I would never allow it to do this illegal activity!!)
I would ordinarily sit at around 70, but when the road is nice and quiet at 6 in the morning, it is fun to put the old right foot down a bit. Nice and safe to do when it's a straight road, with no side roads for PC Plod to hide down.
you sure you weren't in 5th as at those revs my mk2 jtd would be doing 121mph
