Introduced in `1998`, the Bentley `Arnage` opened a very unusual period at Crewe. It launched with the BMW-sourced `4.4 biturbo V8`, then the `Arnage Red Label` arrived for model year `2000` with the monumental Bentley `6.75-litre`, while the early `4.4` cars became `Green Label`. That transition is exactly what makes the generation interesting today, but it also means you need to know precisely which car is in front of you. The atmosphere remains that of a huge traditional British saloon, a long way from the cleaner logic of a Mercedes-Benz S-Class.
