These wheels were purchased and mounted directly from the MB dealer. They were fit onto an S550 Sedan pictured below. The wheels were maintained by my brother using soap and water. They have curb rash due to his wife driving the car, but it is not noticeable unless staring directly at them (you can barely tell they're rashed in the picture below).
They are staggard, although I'm not certain of the sizes. I just know the tires are 275 rears and 255 fronts, so I'm thinking they're probably 9.5 rear and 8.5 front. Offsets are also in question, so depending on the interest and offers generated by this thread I'll look more into them.
My brother doesn't really care if they're sold, if he doesn't sell them, he'll just mount them onto his new car. Turbax has quoted him $115 to fix the rash on each wheel. Local buyers preferred but willing to ship at buyers expense.
Again, these are Calsson Forged 1/16 Ultra lights. They are considered extremely strong and light wheels, also due to the fact of its multi spoke design. He wants $2150 or best reasonable offer, not including shipping, so make some offers and maybe Ill get him to sell. They wouldn't look good on his new SUV (G55 AMG) anyway. BTW these cxome with tires, brand on those are still in question.
Here is a pic of the wheels.
