Most all luxury cars have simular designs these day which has been discussed many many time here.

This being the case it`s about interpretation and evolution of design within the family and how the designers make these qualities stand out.

Remember, the computer has all but become the eye of car design in the 21st century because the computer maximizes the efficiency of design in ways the normal human eye cannot see. Aero-dymanic, cabin room exc with body design all play a part with computer control to minimize space and materials used.

This efficiency controls the foundation of design. The human hand just adds his final touch to detail the end result. This is one of the main reasons cars
look alike these days.

20-25 years ago this was not the case at all. As cars were completely design by human hands (as the designs simply had more "soul") but the design work was no way near as efficient as thay are today.
