(and my extended warranty ran out 5 months ago) Could I save

can someone explain what 'valve guide seals' actually do? Why so much? Is it reasonable to think an indy shop can do it for 30-40% less?

I always heard transmission repairs were most expensive.
What was your oil change interval since you've owned the car?
