as a person who got the extended maintanence for free id say its not worth it. probably 2 x oil changes, 2x wipers, 1 microfilter, maybe one set of brakes (front or rear) and they dont even replace the rotors if they are within spec. all of that you can do yourself for less than 2k.
oh ya and for clutch it should be covered except for the flywheel, but good luck having it fail within the two yr window. if you beat on it, they will take it apart and see that it was abused and not cover. if you drive normally then it should last more than 100k.
