I'm wondering if you could develop a 'cost/benefit' analysis for BMW versus Other battery replaceemnt:

Non-BMW: $180, every 3 years, maybe reduced life due to no 're-programming'...cost $60 per year

BMW: 5 years, $384 per replacement, optimizes life: cost $75 per year.

Just pulling numbers from the air, but IMO the lunacy of paying dealership prices needs to be offset by real value.
