The Servlet should create a CarData object and use the GetBasicList() method to obtain
the data that should be displayed as some kind of HTML list.

Now I'm confused. The "restore" method is being called -even though that does not happen in the code you posted- yet the "carData" map is still empty?
Regarding the createList method: Map.containsKey returns a boolean - which looks wrong in the context of an HTML option. Also -assuming that a car's serial number is the first parameter of the Car constructor- the containsKey method will never return true, because none of the example cars have such a low serial number.
