I looked around and at different wagons when I bought the Stagea.
I talked to a number of guys I know who own Subarus. They all have the same problems - diffs, big ends, oil leaks and turbos.
The Legnum looks good, has good power, but the gear box (tiptronic) is shit! I know a number of mechanics who have worked on them and they all say that the Legnum/Galant gearbox just randomly stuffs out no matter how you service it, and then costs you an arm and a leg to repair/replace.
I decided on the Stagea because of known reliability, good build quality, size, price and the fact that every wagon here in NZ is a friggin' Subaru or Legnum (think for yourself, be an individual, people!)
The Evo wagon is nice, fairly pricey though, and hard to find.
Other wagons I looked at were Mitsubishi Libero (GSR wagon), Nissan Cefiro (front drive) and Nissan Primera.
I guess we are lucky here in NZ with the range of imports we can just walk into the car yard and buy, no waiting for the boat to come in.
On another note relating to reliability, the Nissan CVT gear box in late model Primeras and Maximas is pretty good. But if it does stuff out, it's NZ$13,000 to replace! I was told that by a Nissan mechanic when we were talking about it while I was waiting for my Stagea to be serviced at the dealership. I couldn't believe it, NZ$13,000 is more than some of the cars it's fitted to are worth!
