I assume you want an answer to your question(am I missing something?). 1. Jacking up a car the size of the RX-350 four times and working on 18" wheels is both arduous and, in your driveway, potentially dangerous. If you decide to work the spare into the rotation, hauling the spare out from under is a no fun job. 2. Some people who have given oil change guidance in another thread have recommended raising the front of the car higher than the back; this might require purchasing jack stands, and then trusting them. In any event, it would seem necessary to slide under the car. I am too old to slide under the car. 3. You must take the used oil, 5 or more quarts, and transport it to an oil recycling point. This is potentially somewhat messy. 4. I won't even go in to the brake checking issue.
I can make enough money in an hour at my job to hire someone who's job it is to change oil and rotate tires and check brakes, and still have a little money left over. The person who I am hiring to do this work is grateful; he needs to do this work so that he can support his family and pay me. I must agree with others in this thread that what you get for your $200 for the 10,000 mile check makes it a bit pricey. It would seem possible that the Lexus folks could find some other more acceptable way of !Removed! us.
