Personally, I think the interest has peaked and is on the downhill slide.
Maybe so. The I6 is an anachronism. A few old farts in GM pulled out the old-school whoop-Ass for GMT600, and the bean counters missed it. We were lucky. It'll probably never happen again. Even BMW is going 4 banger.
That said, I'm sure the quantity in junkyards is enough to satisfy the swap market from here until eternity.
