During the briefing scene in "Star Trek - The Motion Picture", one of the assembled Enterprise crew members wears an apparatus on his chest made from the lower fuselage of a Cylon Raider:
"There can be no survivors. So long as one human remains alive the Alliance is threatened."
The Raider isn't the only Cylon model that turns up in STTMP.
If you look at stills of the Vger set parts you will find a ton of basestar models used as detail.
