I think it was good first of all to put the time and energy into such a good looking Plus 4. My guess is that it was damn difficult to make the car look so authentic and traditional. And they did it with all their heart and not half. It's not just "form follows function" like the steel frame. It's letting it look like such a traditional steel frame car. The devil is in the details.
If the new shapes are implemented just as well, we can look forward to beautiful modern cars.
