I do a lot of my stuff as well , tires , brakes , fluids , but the older I get , the less I want to fool with very much beyond that , even though I can and do sometimes ..
There is no good Indy around here that I know of , but I don't stay in the loop on that ..
The dealer here has some good guys and I would take my chances with the dealer before the Indy , as I stand a better chance of having them stand behind what they do ..
A digression in defense of the dealers :
Lotsa people give the dealers the third degree , but in their defense ( I used to work for one ) , their overhead is astronomical and they are in business to make a profit , if they don't make a profit they are out and it hurts everyone in the area . My local dealer isn't perfect , but I prefer him over some of the others I would have to use if he had to close his doors
