Out of the cars you're considering, I'd probably go for the Focus RS.
However, with that sort of cash burning a hole in my pocket, I'd be looking along the lines of a BMW 335d and then getting an Evolve Re-Map on the thing... mmmmm torque-tastic, but then you have already had a BMW. However although the service costs are slightly higher, they are at far longer intervals than most of the more focused stuff in your list so I think it'd even itself out to a negligable difference in the long run.
Cheers,
Grant
