Sure it's good, Subaru is a successful company and has a very loyal following, much like any good brand. They've been pretty consistent with just plain, good, reliable cars for a long time. Just like some families will only buy Honda, or Toyota, some will only buy Subaru. Hell, 5 of my last 6 cars have been Subies, and my wife is on her third. We've been happy with all of them.

The boxer isn't a perfect engine, but its built well and has some unique characteristics that work in its favor. The only real reliability problem I've seen with any consistency is the head gaskets around 80k miles on the now outdated EJ blocks. Maintain it well and fix things as needed and it'll last a long time, any engine poorly maintained won't last long. The FA20 is a new design, but with modern engineering there's no real reason to believe it won't last 200k+ miles. It's had a few teething issues but even old "proven" engine designs will occasionally have problems.

I'm pretty sure the enginners, designers, and parts bins from BOTH companies were availible to everyone working on the project. A joint project is a joint project.

As far as I'm concerned the joint project was an overall success and resulted in a quality product. I could careless who takes the majority credit for the car. I'm just happy that I am fortunate enough to be able to afford and drive one and will continue to enjoy my time with my twin.
