I have the removable hardtop from my 2003 E46 M3 for sale. Exterior is silver, interior headliner is black. Condition is probably near mint, or close. Everything works fine, lighting, locking cams, defroster, etc. Asking $1950.
That will include a neat home-built lifting cradle, a power winch for one person removal, the floor dolly for storage, and BMW cover. The cover has a small tear in it, but seems to work well. PM if interested, and I'll shoot some pix. Thanks.
