Hard to answer any of your questions, since this car is a true Japanese import. Price comparisons are practically impossible and reliability is difficult to determine since these versions were not offered and are still not prevalent in North America.
However, I am drooling and it would be difficult to hold back on making an offer...I would be willing to make the purchase if I had an independent Subaru mechanic who was confident with Japanese spec cars.
Let us know what you decide to do!
