Hi Folks, I have a 1998 Lexus LS 400 in superb condition. I need to do the 60,000 miles service and so far the dealers that I contacted wanted nearly $1,000 for a service that did not require valves adjustemt and $1,500 with valves adjustment. My regular mechanic says no valve adjustment is needed. Can any of you educate me briefly on what needs to be done on such a car at the 60,000 miles service, i.e what is really needed ? Your feedback is greatly appreciated.... Nouri
