You bought it at the wrong time. 100,000 miles is the usual interval. Looks like you will have to invest $500-$700 getting it changed. Now you know why the previous owner got rid of it.What is the service interval for a timing belt? I've got an owner's manual with my used 05, but not sure how to tell when to replace the belt. The schedule is based on numbers/letters, but I couldn't find how to reference them. I just got an 05 used with 111k on it. Thx.
