Little bit high but it depends on what's being done. Coolant, brake fluid, tranny and diffs, sparkplug replacement all take time to do. You can save money by doing easy things yourself like tire rotation, cabin filter etc.
I wouldn't skimp on any of those items if you're planning on keeping your car for awhile. Ha ha you have no idea what a 430 costs to service. Most never see 20K let alone 60K.
