Hello, I want to buy a Smart CDI. Possible an annual car. As an annual car there is so far only the 33kW version. It is the question if I still wait until there is the 40kW version as an annual car. More power is nice, but not decisive questions: 1. when was the market launch of the 40kW CDI? From when was the delivered? 2. what are the differences between the two? Of course the power is higher at the 40kW. 3. the 40kW CDI has Euro5, what does the 33kW CDI for a Euro standard classification? 4. the 40kW CDI has a closed particle filter system. Does the 33kW CDI have an open one? What are the differences of the systems, what the advantages / disadvantages? Many greetings ge-el-ka
