As said above, it can easily be done in a day.. My father-in-law and I spent a day teaching outselves how to change the clutch & gearbox on the other half Spaxo, granted it wasn't a v6 beast but the process is the same!
Will be doing the clutch on my derv soon, I think it's on its way out
Has done 94.5k miles in 4 years, so isn't doing bad!
