Subaru's AWD system relies on the electrical
control a lot. When it works, it is terrific. However, I am not a big fan of electrical control system. Personally I felt that the system will become unstable and dangerous if the car is getting old. I never owned a Subaru before so I really cannot tell if my suspicion is true or not. But I think anyone who is considering buying a car with such a system should do more research before making the final decision.
