Basically, I know absolutely nothing, and I mean nothing about cars. I don't know the characteristics of the various brand/model. V6 sounds more like a Japanese boyband than an engine. I don't know what the 2L is supposed to refer to. GT sounds to me like a rip off of nVidia's mid-range graphics card. Okay I am kidding, I am sure it's the other way round, but I still don't know what it refers to. Different type of suspensions, brakes chassis (in fact, why can't see kick-ass looking chassis with a 'standard engine' - whatever that is). You get the idea.
So what is the best way to get up to speed? Are there any well written, concise guide out there? Frankly speaking, I don't really get excited reading about cars (so well written/concise is a must). Yet I am learning to drive as a possible future need, and I will need to know a little so that I can pick a car for my needs when the times come (which is most likely not one that can break the speed limit in the shortest time as possible, rather, something comfortable, gas efficient and safe; doesn't hurt if it can go fast, but it's not the whole point for me).
