Definitely not worth the extra money for a specB. Subarus are designed by engineers, not by people who actually use the cars on a daily basis. Would I buy another one again? No, with emphasis! Too many annoying and poorly thought out features.
Good safety record
Steering wheel audio controls should skip through preset stations, not search for the next station. Eliminate the constant seat belt chime. Eliminate the "stutter" when accelerating. Make sure everyday drivers test the car before releasing it.
