Coming from american muscle cars and chevy trucks, I've only been with the bmw brand for a little over 3.5 yrs. I know they are completely different and some of my methods work for chevy's and may not work on bmw's. But I look at it as trial and error as well as a learning lesson. My philosophy has always been, if you're not making mistakes, you're not learning.

No worries.
Yeah, there is a big difference between maintaining a modern BMW and a muscle car or a Chevy truck. OE plugs can go 100,000 miles, OE oil and filters have been proven to go up to 15,000 miles with no signs of extra engine wear, etc. Apples to oranges.
Also, seeing as we are already way off the original poster's question regarding spark plug intervals, I think you are going to be waiting a long time for your m62 to die. Especially, if you are maintaining it properly (or over-maintaining it). More than likely the rest of the car is going to fall apart around it. If it does fail though, have you looked at Bavarian Auto Recycling for rebuilt engines? They come with a two year unlimited milage warranty and many new parts. Last I saw, you can do some simple performance upgrades during the build as well. I am not talking anywhere near 600 horsepower, but they can do the following and pricing should be about half (give or take) of the $25,000 you were quoted;
Upgrades include flow tested CNC porting, hand polishing, and Bavarian Performance Camshaft an increase over stock.

I would never personally put a LS, or any other brand of motor into my BMW, but that is just me.
