top ten bmw site...my own

[FastM3]

im thinking of making a site like that other top ten bmw site, but they only show e46's....i was thinking that there should be a site for almost all the models and try it make it big then expand to top ten euro cars by brand and models and so forth...

but for now im thinking of doing a bmw site, that'll have pics and mods of all the people who enter their car...anyways i just need to know 2 things...

1- what are all the "E" classifications?

2- does anyone know any of those shorter named url's (eg. cjb.net) but without pop-ups and ads?

thanks for your help guys!
