Re: to rev or not to rev???
I've regularly (probably a few times on each journey, sometimes a lot more!) taken every car I've ever owned to just before the redline on gearchanges, in all gears, though I've only actually hit the limiter a handful of times, ever. Change up just before for a smoother drive! On a properly maintained and warmed-up car, using decent synthetic oil, it is no problem - modern engines can handle being run at the redline for many thousands of miles and are tested in this way. I have never had an engine-wear related reliability issue in any of my cars. Some sensitivity with clutch and gearbox is needed to not damage the drivetrain, but the engine should be fine.
The 2.5 V6 156 I had was the smoothest revving car I've driven, and when pressing on all gearchanges were at 7000rpm. After 90,000 miles of such treatment the engine was better than ever and using less and less oil, it was just running in when I sold it. Don't worry!
