I'm looking for some good reference manuals for my car (seems kinda banal just calling it a car) and would welcome any input. My 325i convertible, with the nifty little ashtray and windows which move without me even pressing a button, came with a Hayne's manual. Hayne's and Chilton's seem okay, I've used them on different cars but they ain't great, and Hayne's doesn't have anything in it abouthe top. The best manual I ever used was a factory service manual for my Corvair, are BMW factory manuals available and worthwhile? It seems that Bentley manuals are referred to a lot but reviews I read on A****n say there is a lot to be desired and the thing is pricey. Has anybody subscribed to and used alldatadiy.com's service. I looked through their demo and one thing I really liked were the exploded drawings with part numbers. Thanks for the advice.
