Well, the only way to prevent this is rather simple-you need to add weight to the back of the car (basically, put more weight on the back axle). To be honest, I have driven the car very hard and have only had that problem once-but it does happen earler than you would expect. The best advice I can give, is if you get one-get a feeling for it on curves before you take them fast (basically, don't take your first hairpin turn at about 70-you'll have a problem). As you slowly begin to take turns faster and faster-you begin to feel where taking it to far is (basically-you can feel it slowly start to slide around in the back). But, if your really concerned about it-just put something heavy in the trunk-that should help some (plus, the trunk is much good for anything else anyway ;D). Also, another thing I have found that helps is to keep your gas tank rather full-that extra weight helps too.
Another thing you should know about the Camaro before you think about buying one is it's handling in icy conditions. I don't know where you're planning on moving to, but ice basically takes advantage of this problem and makes it worse. I have driven it in icey weather with no problems at all, but I have seen Camaro's destroyed because of it. Anyway, thats just something else to think about.
Personally, I prefer the eariler 4th generation model (1993-1997) over the later one (1998-2002). I think it's a more areodynamic look since the front is more pointy-but the later one's have cooler looking front lights. But, my opinion is a little bias since I have a 1996. Personally, I have been planning on "upgrading" to an older Camaro in a few years (one reason because i like the early design better is why I'm not going for a newer one). Actually, here's a pic of the one I want to get:

Anyway, I hope that helped a little (I know it was long)-but if you have any other questions let me know, maybe I can answer them
