4 months down the line and the clutch is really a wear and tear item . IF its the clutch plates or a wear tear part ,
Customer use can cause this to fail .
Only you knows if under your pre sales testing the clutch was fine and working as should .
Agreed a warranty on 3 months then its 3 months , not 3 and a bit or 4 , as there would be no point in saying 3 months would there , A positive no its not covered and its been working fine for 4 months and how ever many miles the customers done .
Maybe they will ring to see if you would , maybe they wont ,
A firm NO sorry warranty expired 4 weeks ago will be expected . Not our job to let someone loose on a clutch then pay for it .
I had a guy buy a small car off me once and moaned about the clutch , I told him straight its your car your problem 5 months down the line , we have a workshop so offered it at a lower rate but when we got in there he had proper ruined it , Ripped the thing to pieces.
Dont fold or they will bleed you dry
