when recommended isn't recommended

So I took my car to the dealership... second time since I got the car in 2001. I figured that I would ask them to do a few of the recommended maintenance things that I never bother to do. Basically adjust the valve clearance, replace the ABS high pressure hose, replace the ABS fluid, and inspect the SRS. Of these things the only thing that is still recommended is the valve clearance. No maintenance required for the ABS or SRS unless there's a problem. Great!

Why the discrepancy? The only thing I can think of is that my car was built before they knew how long things like the ABS or SRS would work before breaking. Now they advise to stay away from those things. Leave it alone unless there is something wrong. I guess it's good enough that I already fixed my ABS thice (replaced three sensors).

So why bother bringing it in? The valves haven't been adjusted in AT LEAST 70,000 miles (although they seem fine), they're fixing my A/C (which I don't have the time or the facilities to deal with), adjusting the rear caliper (because I'm lazy), and they can check out why my car has no power on a warm start on a hot day. But I didn't ask them to fix it. Just tell me the issue and I'll deal with that myself if needed, or do nothing. Not worth paying labour to fix that.

My car should have 170,000 miles on it by the end of the summer. Nice.
