###Pros:

1. Correctly uses inheritance, for the most part.
2. Good namespacing.
3. JavaScript properties are sort of advanced. Nobody uses them though.
4. Good formatting.
5. Completed sections are all error-free on their returns.

###Cons:

1. this.name = n ? n : ''; is totally weird. If it's supposed to be a default value, it should be n = n || '', but '' is null anyway, so it would seem that it should actually say null and not '', which would be an untitled vehicle (?).
2. Generally, JavaScript classes have parameterless constructors.
3. Overkill with the property getters/setters that are incorrectly overridden, so it confuses the intepreter. E.g.: Scopely.Instances.Motorcycle {name: "", name: "", _seats: 1, _wheels: 2, info: function…} from Chrome.
4. info() could benefit from a knowledge of underscore's omit.
5. I wouldn't scope this either, but it would be nice.
6. All the funny JavaScript properties and setters. Just not very idiosyncratic.
