I have a set of 4 mercury silver Volk center caps. Made to fit the 19" TE37 and CE28 rims. Might fit other volks, buyer to verify.

I bought these brand new, so I know the entire history. Basically had them on my TE37's for a few months, car isn't even a daily driver (average about 2000 miles in a year now). All O-rings intact and in excellent condition. The original O-ring grease is still present.

There's a few tiny nicks from road driving. They're hardly visible, and the biggest one was only visible after I enlarged the pic 500% on my 15MP Canon DSLR with a zoom lens.

I have feedback here and on the g35driver forum (E_K), and 100% on ebay as ekg_squoil as a buyer and seller of multiple items.

Asking $150 OBO shipped in the continental US, or $140 picked up in socal.
