Online shopping for Automotive Technology from a great selection at Books For Everyone. It is a broad area, it is like saying how to be a good programmer (financial programming is different then web development which is different then web design,etc).

Figure out which area you are interested in, powertrain, body, exterior design,safety, interior design, etc. Then go to SAE International as well as your local mechanical engineering school to pick up technical information about engineering principals. There are only a few automobile engineering books and those are published by SAE.
We sell a variety of Automotive eBooks and some hardback books too. Always adding new books on a daily basis.
