30K maintenace worth it from dealership?

I have a 2011 Platnuim Armada and i am at 31K miles and wanting to know if getting the 30K premium maintenance is worth it at my local dealership. my dealership is charging about $425.

I want my armada to last me as long as without having any major malfuction so is the 30K maintenance worth it from the dealership?

I have not bought an extended warranty either and still contemplating if I should get one as well.

Thanks for any input.
