These are the modular BBS made AMG wheels for the CL55; there were very few sets since they only came on the AMG CL and were sold in dealerships as accessory wheels. These started life as RT178 and rt179 so:
(2) BBS AMG RT178 17x7.5 et37
(2) BBS AMG RT179 17x8.5 et34
Selling the centers for $900 shipped in the US; if you want the barrels which are one piece hoops they are free but add whatever the shipping difference is. They were badly curbed and inexpertly sanded out so would need CNC work probably to get back in ok looking shape. I found 3 wheels ten or twelve years ago then lucked into the fourth on a display rack at my local MB dealership although it had been damaged as well just hanging there for 15 years.
