Having driven a '10 3.6R over 105K mi, I have had zero issues, aside from replacing a broken volume switch on the steering wheel. Oil consumption is always monitored with no problems. 40K mi in 2 years is heavy use, but I'd conclude any serious issues would have been wrung out already. I have never collected on any extended warranty anybody ever sold me. It's a bad bet. Save the money, maintain the car faithfully, and odds are, you'll be happy. It's a Subaru. If you get nervous later, the resale value is fantastic. Trade it in on a new one.
