Yep - bought the 18" M-Pars from them about four years ago. Came with BMW center caps and ///M stickers (which fell off almost instantly), but you'll need hubcentric rings.
The finish was clearcoated, machined aluminum faces on the spokes and lip. I would say great quality, though the metal was a little soft and had slight bends over the years from potholes and such (typical for KO wheels). I first mounted them on my E24, then onto a pair of E28s before replacing them with staggered 18" style 32s. Sold them (with those same tires) on CL well over a year ago.
As I recall, I paid ~$1,200 with tires, delivered. Felt it was a great deal. Still do. Happy to recommend them.
