This guide will give you an "idea", of what kinda car you may be trying to discuss. I couldn't include every sedan/coupe/hatchback combo, or account for all the different ones around the world. This is by no means a full list of all the cars in each generation, just a sample from each. If all else fails look at the headlights they "should" be similar for each car in any given generation.
