The 400 HHR model was a new model based on the Honda Domani, which was apparently sold in Europe as part of the Honda Civic range as a hatchback and estate (wagon). The new 400 model was to be separate from the 200 range. Rover wanted to have more input into the car as it had with the R8, but Honda had different ideas and the Domani was offered pretty much as it was. All I can say is that Rover had better designers when it came to aesthetics than Honda did. Rover did eventually get some input into the 4 door model and was the better for that. It seems Rover wanted a bigger car but had to take what Honda offered. Rover in fact pitched the HHR at a class larger than it was, but the strategy fooled no one.
As for sales by countries, some are listed below:
This was not the model it should have been. Rover needed something larger, especially the Hatch version, but the company was tied to what Honda offered. Overall quite successful.
