To be honest, a 'ragged' car and a car driven hard are two different things.
Let's face it most cars get driven quite hard and most engines are designed to rev to near their limiter. I've seen Ford running an ST engine on full revs for 3 months and equivalent of 150k without a problem. A bit of intermittent high revving will do it no harm, in fact now and again it'd do an engine good to clear the crap out with a bit of a blast.
You could buy a car that gets the odd bit of spirited driving but if it is warmed up and driven correctly it will do no harm. A car that is 'ragged' is a car that's driven hard from cold by someone with poor car control, not servicing it properly, not checking oil/tyres etc.
Some of the worst drivers may not take their car over 4.000rpm but they could ride the clutch, hit kerbs, not service their car etc. That's a car I wouldn't want to own. The same goes for a chav that gets in their car, takes the car to 6,500rpm from cold on every gear change, never washes the road salt off, hits pot holes etc etc. Again I wouldn't want a car like that either.
A balance of driving properly, warming the car up, servicing and general caring for the car plus the odd bit of spirited driving with the revs going a bit higher is ideal. That's how I do it anyway! haha
