As an engineer, I don't like the idea of metal slipping on metal, even if its in a fluid bath. Several manufacturers have attempted to install CVTs in their vehicles, all have failed.
The problem is not with the CVT design itsself, but that the manufacturers assume that the end user is more intelligent than they really are.
If the general population babied their cars the way Subaru hopes they do, no CVTs die. If American treat their new CVT-powered OB like the then-new STIs in 2004, yeah, everything is going to get replaced at some point.
Subaru offers a 6 speed on legacys and OBs now, go with that. Tried, true, better mileage, more driver control, safer. End of story.
