I also get the "bigger picture" thing, but if he's willing to short change a "brother", what's he doing to others who don't share similar faith & values? If you don't at least have a conversation about it with him, then your sneaking around to get the Camaro seats done by someone else will potentially cause a bigger rift down the road. It's really none of my business but I find it quite annoying when supposed friends take advantage of a situation. He owes you an explanation, if nothing else.
