hey I got 33k miles on my MS3, just had the primary O2 covered under warantee, would have been $611 normally. I can get 3 star waranttee for 100K miles for $1900 ($100 deductable) or $1700 ($200 deductable). I do most of my own work on the car, just not the really big stuff. Is the extended warantee a waste of $$$ ???? I have until 35K to sigh up. Just wanted to see a few peoples thoughts on this. Thanks
