What are common repairs and their costs when the car hits 100,000 miles?

yes, I did read the fine print and most of the "big" things are covered in full which is good. I just don't know how many of the "big" things are likely to go wrong. It seems Subarus are pretty reliable, but then again, timing belts, struts, anything with the computer or electronics can be costly. Just don't know. Is there a reference anywhere to typical kinds of repairs that often occur in the mileage range of 100,000 to 150,000?

There is no typical repair that 'may' occur at any mileage!... Timing belt should be replaced before 100k.. There are a lot of loop holes in most of these warranties... It totally up to you!!... Try Google to see if Subaru has fixed their leaky head gasket problems... That's a problem that 'might' arise, however $3,000... Well, it's your call... But then again, it's a gamble either way, I guess!... While on Google, look for a Subaru forum and check it out... Lot of owners info there!.. That's better than a repair site because it more specific to problems with a certain make/model...
