Been looking at Cars.com and Autotrader at SL550's and see that there are a lot of '09's and '11's available for similar prices. Are there any major differences between them? I know that the '12's got a major update but don't really see any differences between the earlier models.

Also saw one that has black interior but has contrasting stitching. Was this a special order or part of the Designo package?

Any help would be greatly appreciated.
