Hi guys... My 2006 IS350 is about to hit 30k miles, and my dealer wants about $650 for this service! Looking at the maint. manual, the only replacements that's required by Lexus is the change of the engine oil and filter, air filter, brake fluid, and air conditioning filter, the rest is all "checking" vs. "replacing" on different things. I was just thinking about getting the oil changed ,and doing the filters myself... Any thoughts? Thanks.
