Technically speaking (if I'm not misktaken :getmad: ), it's the C-128 that's the direct predecessor to the Amiga. It was the last of the 8-bit Commodore line. Even the case design was slightly modified and used for the Amiga (the Amiga 1000 closely resembled the C128D and the Amiga 500 closely resembled the C128 wedge shaped unit).
