Could someone explain the different generations of Subaru Legacy, and what changed with its incarnation? Like, engine, EFI, whatever.

 

I am currently enticed by 1994 or so models, which are old enough to be inexpensive but not so ancient as to be in poor shape, and post-93, they should have the new AC system (if it works like in domestic cars).

 

Of course maintenance is everything, and '94 models can certainly be abused.

Another question, is Outback (Like '96) a version of Legacy or a different model?

Check out this site. You will find information about models, features, options, changes, etc.

 

I'm not sure just when Subaru switched to the 134a a/c fluid. It was around that time IIRC.

 

The late 90's Outbacks are essentially a modified Legacy wagon. It is the same platform. Different bumpers, raised roofline, raised suspension, hood scoop. It got the larger of whatever wheels / brakes etc were available. It's really not "that" different, but it looks it. And it took on a life of its own as one of the first "cross over" vehicles (SUW, Sport Utility Wagon), partly thanks to the Crocodile Dundee ads at the time.
