100k Service

[jjsea55]

Just crossed the 100k mile threshold on my '06 V. For anyone who has amassed this amount of milage on their V's, how necessary is it to perform all of the listed activities that Cadillac specifies at this level of miles? I've replaced the engine air filter recently, and could see where it may be time for a transmission fluid change (although no shift issues)... but what about the spark plugs? Have never experienced any misfiring or drop in mpg. The Cadillac dealer wants both arms plus a leg to perform this service. I'd most likely opt for non-dealer service. Hoping to get some input from those who've made it this far. TIA

I think it was about 160000 when I changed the plugs in mine. No issues. Really not hard to do takes about 20 min and a star driver, along with the plug socket.
