The Trek dealer offers lifetime annual tune-ups to include adjustments, wheel truing, bearings repacked if not sealed, cassette and chain cleaning. All included in the price (full retail of course).
All of this sounds great, but the "adjustments" involve knowing which way to turn an adjustment knob (it takes two seconds and shouldn't need to be done more than once), well built wheels should never require truing, finding an unsealed bearing on a bike could take some work these days, and if you don't clean your chain fairly often, you're going to have a short-lived drive train.
i.e., it looks like a great list of "free stuff", but it's really not that big a deal.
