I'll admit I'm not a big dealer fan for basic repairs. Thus, I think the prices quoted for the services recommended are excessive. At 30k miles, however, you should do each of the recommended services except, maybe, the carbon clean-out. I'm not sure what this even is. Could it be the carbon filters for the air circulation? Buy them and install them yourself if it is. You shouldn't have much carbon build up in your heads since your using Premium gas. As for the tire rotation, balancing and alignment, take the car to a local Goodyear or other tire oriented specialist. I assure you it will be cheaper than quoted at the dealer. Also, Power Steering Fluid, much like Brake Fluids, are corrosive to the rubber lines they are in. I have heard of flushing the brake fluid lines for this reason (it also prolongues the life of the master cylinder and disk calipers) but never the power steering. Seems like it makes sense for similar reasons... probably have the local mechanic who does your rotations and alignment also change this fluid (and brake fluid too). In fact, many of your national chains like Goodyear, PEP Boys, etc. will actually print out Lexus' 30k mile recommended check-up service schedule and do exactly what the dealer will do for a fraction of the cost. Save the dealer for the bog stuff (computer related, hard core engine related, etc.)...
