355 Rims

I have a set of 355 rims I purchased a while back thinking I wanted to upgrade to the newer rim look, however after mounting them I can honestly say I like the orginal look better, I own a 94 348 speciale 15of 15(I love it black). Anyway I now own (4 )355 rims that I dont need. My understanding is that these rims are factory ,however I dont know what to look for to confirm it ,regardless they are beautiful rims. I am asking $1500 for the set( firm!) which is $500 less then I paid for them... my loss I will post pictures when I get my camera back sat/sun.Email me at [email protected]
