My super hearse is getting worse and worse, 115k on and the clutch/flywheel is about fooked.

Do I bite the bullet and spend hundreds getting it sorted (how much?) or chop it in and spend a few grand to replace it with a newer one?

Been a superb work horse for the 3 years/60k i've done in it, so would get another no problem.

It's a 2004 130 BTW.
