So I brought my 2014 C650GT into the dealer for the 24K service, and boy am I thankful that I purchased the Priority Maintenance Plan from Western Services Contract (Long Beach BMW, my dealer, had just started carrying the service). I paid about $2K for the next 6 factory-standard services, and while I saved $400+ on the 18K service (according to the service manager) when I saw the bill for the 24K service I almost plotted - a tad over $2700! And that was just the BMW-prescribed service - no tires.
So for those of you nearing that milestone, be prepared!
