Making FAQ Section for the 3-series

I've seen alot of repeat posts of people asking for pretty general information about the 3-series, and I decided to make one big post to encompass as much information about these cars as possible. So im presently taking suggestions as to what people think should be in this new FAQ section. Send me a PM with any advice of what you think should be included. I'd especially like pics of the E30, E36, and E46 that are capable of being shown in a post.

Thank you in advance-
