If you've had it documented all that time that the problem exists they still have to fix it regardless of mileage since the problem was documented and not repaired long before the warranty ran out. Not sure how the clutch thing is going to work out in getting repaired since they are an expendable item but since your flywheel is warped that would also be a part of the problem and may mean they have to replace the clutch for free.

BTW, what are they making their clutches out of for that price, gold or platinum? Good luck and just be persistent and hopefully you have a friend that's a lawyer if you need one. I just hate car dealerships.
