The only one that doesn't break is the one you use as a display piece.

I have a PTW body who's motor mount broke and have seen ones that have gone down.

With a good maintenance schedule you can make it last longer but it will still eventually break internally, or if you're too hard on it break externally as well. Think of a bike, you still have to do maintenance on it every so often and there are maintenance schedules based on the mileage you put on.

If you want something that's fairly durable and requires longer maintenance intervals get a TM and slap on an FMU kit on it (beware you're going to get lower gas efficiency due to the increased weight of the FMU kit), a KJW, or a KWA/KSC.
