I don't think there is much to choose between the trims, it's more about spec, though personally I prefer the Black Editions without the chrome.
Nonetheless, I don't think I could live with all the controls, the heating for example, being controlled from the touchscreen, you must have to take your eyes off the road to use them. I'll be avoiding any cars without at least some traditional controls (BMW nudge nudge), but also reserve the right to totally change my mind and go for one
Also, you know this already, they are more expensive now than they were 2 years ago, so not sure we can use the word 'value' for D5s
