Does anyone know where I can get a repair manual for my 87 735i? The closest I've come is Hayne's manual for the 5 series 735i in that year. HELP!

Sad to say the only "published" maual for the e23 series is Chiltons. A lousy book, but the only one around. You might want to invest on some factory manuals. Check ebay, they come up from time to time. Here is a link for a source for the manuals on CD:
