I would say CONSTANTLY driving near or at redline. I'd say anything above 4k RKM is not needed for normal driving, of course you can take it over that for some fun from time to time. The powerband is from 4k to redline
Obviously the more you push the car to it's limits the more likely it is to break down on you.
So I guess beating on the car would be taking off from every light like you're racing someone, banging gears, etc. Of course you've gotta keep up on maintenance. Always check your oil and make sure everything is in good condition under the hood. If you keep on top of all basica maintenance issues you shouldn't have any problems. I'm not saying you should drive the car like an old woman, though that is one way to make the engine last forever. I admit to putting lots of hard miles on my car, but when it's all said and done I do my best to make sure everythings working as it should be. That's why so far, it's still running well. Alot of things can be considered beating on a car, most of it should come to you usign common sense and being reasonable with the car.
