I know I can call the dealer on this (and most likely will), but
what's the frequency of those of you with  higher mileage
Lexuses normally change  your timing belt?

I see many people with well over 100k on their cars that post
to this group and I'm just curious if or when  your changed your
belts?

I was looking at some earlier model SC300's the other day and
most of them are routinely in the 130-150k mileage range and,
unless they have a Lexus maintenance history, it's highly likely
that if I had purchased one, I'd have to expect to pay to have
the belt change.  And, for those of you that *did* get a belt
change, did you do it at your dealer or have an independent
shop do it and how much did it cost?

TIA!
