Congrats on your car, and I applaud you for the DIYs.
I've done a few very simple things on my ride and wouldn't have it any other way. There's a time and a place to use the dealerships. And none of them are the same. I still cringe when I have to pay ~$270 for an oil change in between the intervals. 15000 miles is just obscene for scheduled oil & filter changes.
Oh btw, I think it's time for you to open up shop. I'm sure a lot of people can use your help.
