If you don't mind building and configuring your Mercedes-Benz CLA in German and using Euros... oh, and also with some options that likely won't come to the states, then we have the link for you.
You can visit Mercedes-Benz's German website and the full Konfigurator tool is available for the CLA Lineup. There are a ton of high quality pictures, lots of information and options for the European CLA. Unfortunately here in the states we may not see all those options but until MB USA gets their act together this is the best we can hope for.
Here is the URL to visit to begin construction of your dream CLA today: Mercedes-Benz Deutschland - Konfigurator - CLA-Klasse Konfigurator
