Decide which cars are 'cool', and which aren't, by placing photographs. The categories are Sub Zero, Cool, Uncool , and Seriously Uncool, a vehicle's placement has nothing to do with how good or bad a car it is. 
Give an exlaination as to why is that car in that paticular segment.
Rules and Tactics
There are some rules to the Cool Wall, although all seem to be flexible:
* Motorcycles are not allowed in.
* Supercars are automatically uncool or seriously uncool, as there are few cool people who can actually afford them. An exception is the Koenigsegg CCX which is cool on account of its scariness(it scares you so you start respecting your life). Two other supercars, the Bugatti Veyron and the Mercedes-Benz SLR McLaren are also classed as cool
* Diesel-powered cars are never cool as, regardless of how good they are, their only purpose is to save money.
* Small European cars, such as the Peugeot 206, are generally cool. Except MINI.
* People carriers are never cool, because they're not cars people want to have; they're cars people need to have.
* Everything with a ? koda badge on it is considered to be seriously uncool; the picture of the ? koda Fabia represents all ? kodas.
* German Cars, particually BMWs and Mercedes, are always uncool.
* Cars can move up and down the Cool Wall depending on new insights and theories as well.
