Hello: I'm a newbie here and this is my first post! I have never owned a Lexus before. However, I'm working an a "potential" deal for an 1996 Lexus LS400 with 47,000 original miles on it! This LS400 is factory original in every way! This car runs and drives great and seems to have alot of power for one of these(unmodified)LS400's! My question involves the expected reliability of the timing belt, before replacement might be needed? Please answer this question, in regards to a stock(unmodified)LS400? At this point, I just want to know just how good and reliable(Or, unreliable?)these timing belts are-since the proceedure appears to be complicated for replacing the timing belt on these LS400's? No, the timing belt on the 1996 LS400 in question, doesn't need to be changed now-but, I'm just wanting to know what the expected lifespan(In normal driving!)would be, on the average, for these LS400's? I mean, on lot's of less expensive cars-these timing belts are just "throw-away" belts and require fairly early replacement! So, are these LS400 timing belts the "throw away" type-or, are these belts of higher quality and would last much longer, for their overall life span, before "requiring replacement? Please explain and clarify your answers? Thank you!
