The life of any machine depends on the user. If you take it out and hit a wall, the newest machine will also die instantly.
Coming to your question, Subarus are very fine and reliable cars. I've owned a Forester for more than 10 years and never had any major problems with it except the "check engine" light staye on. I've had mecahnics check the whole car about 3 times and found no problems.
The trick is to change oil, check tire pressure and all the guages regularly and wash the car especially in winter to avoid the salt eating away the metal. As the car gets older it is better to run the engine idle for about 5 minutes before driving and there it is, the car will be loyal to you, possibly forever.
If you dont take care of it, it will not take care of you.
