I noticed a question for R3 info. This may be common knowledge, but if not, according to Langeworth(1979), the nine R3s were:#R5089(turquoise,4-speed),#R5237(black,4-speed),#R5394(white,4-speed),#R5532(turquoise,4-speed),#R5546(gold,4-speed),#R5593(grey,automatic),#R5625(black,automatic),#R5642(white,automatic),#R 5643(white,automatic). The R3 option listed for $1,031.
