OEM forged wheels: NLA, expensive, and the stepped-barrel detail

The factory forged wheels are prized and increasingly unobtainable, with owners reporting a single replacement front wheel costing around $2,500 (and quotes near $20k for a full set) and dealers describing German stock as nearly exhausted. Enthusiasts also note early cars used stepped-barrel wheels to clear the front steering knuckle, and that the factory face is mirror-polished while the spoke windows are brushed, which makes refinishing hard to replicate.
