For example, the 15" wheels pictured on this 98 Forester, which I believe is part number 28111FC050:

... currently lists for $96.92 each from a dealer. You can buy a brand-new set of these wheels for under $400.
Considering that many Subaru alloy wheels list for more than that for each individual one, that's a REALLY good deal.
I believe there is an SG Forester 16" alloy wheel that is similarly priced, but I'd have to check on it.
I'm actually buying a set of these exact wheels myself for my Legacy.
Just letting you guys know, in case you want some nicer OEM Subaru wheels.
