Yes, I did recommend Mike's schedule and often do. In context it was the right thing to suggest. I don't recommend it every time, and sometimes would strongly argue against parts of it. Back to the radiator example for instance. I have never recommended a customer change their non-leaking, non clogged radiator just because of mileage. But if that same customer told me they were driving to their new home in San Diego (from NH) with their elderly mom in the car, and their car had 120k on the clock and cost were no object (it isn't for many of my customers) I would suggest a new radiator, among other things.

I was using a 5 year ownership span with the EPA reported national average 13,000 miles a year. Even going with your 80K, that's less than half the lifespan of the vast majority of engines. I don't think it's enough to say that 15k intervals will work in all parts of the country. If sunny is correct about 15K intervals on the E46 then that would be additional evidence in your favor.
