my clutch has started slipping erratically,sum days no slip,sum days slipping in second.I just been quoted £500 to replace clutch,which includes replacing front oil seal which may even be causing slip,not worn clutch.They say 6-7 hrs labour all in(alfa specialist),does this sound reasonable.
Never had it done but it does sound about right - for a Alfa dealership that is.
Full Alfa Price for the clutch kit is about £200, you might save some money with pattern parts but beware of cheap and nasty parts which wear out faster. You may find that competition parts cost the same as Alfa - worth a look if someone else here will recommend a make for you.
That leaves 6 hours at £50 per hour. That is the same price as a Alfa dealership! Did you say specialist as in independent specialist or did you mean an Alfa dealer? Why not call for a quote from some reputable independant Alfa Garages.
