As a former Lexus tech and service advisor, let me throw in my opionon. You do need the 30K service, but not necessarily everything the dealer is trying to sell you with it. You need exactly what is outlined in the owners manual. Oil and filter change, air filter, cabin filter and brake fluid replacement. That's it! All the other stuff, like alignments, power steering flush, fuel induction service, is not needed. These are additional services recommended by the dealer, not Lexus. Make the dealership follow exactly what is in the owners manual.
