Well my opinion is prejudiced, concerning any kind of FUCHS designs (which i like, of course).
These look pretty good...and if Otto Fuchs wouldn't offer any new ones, I am sure I would have gone with aftermarket ones like those. I've seen a Boxster trying to fit old 16" (?) Fuchs wheels, but that looked like crap.
And yes the OEM Fuchs are PREMIUM priced, no doubt, and therefor will be a rare sight on a Boxster. I was just crazy enough and could not say no...
Only thing which really strikes me: The OEM FUCHS seem to be really light weight wheels compared to aftermarket ones...that might be MAYBE another reason to justify that price, or ahem...pay that price...lol.
