I hv an 07 w 133k right now. This car has been issue free, mechanically. Overdue to get plugs changed and rear diff fluid changed. Got a call in 2 Lexus,as i write this, for a price. I'll probably wind up doing it myself. Just finished replacing rear struts myself. What an improvement! But, now became obvious I need 2 do fronts, as well.
This is all, obviously, regular maintenance. I've owned this thing for almost 5 years, and put 65k on it..........best car I've ever had, hands down!
