What is the difference between the Aston Martin DB6 variants?

The DB6 features a longer wheelbase (by 3.75 inches) and a distinctive Kamm tail for better stability. For buyers considering the Aston Martin DB6, that matters because it affects how easy the car is to live with, whether for commuting, family use, long-distance driving or ownership costs. The useful way to read this is not as an isolated specification, but as a clue to how the car will feel in real daily use.
