hi everyone

please bear with me as i'm new to your forum. i'm seeking advice on an issue i have with the clutch in my car.
i only bought the car 2 weeks ago only to find the clutch was slipping (vendor completely washed his hands of me and the car)
i have had a new clutch fitted (£450) only to be experiecing a similar slipping problem.
the guy that fitted the clutch unit said that it was the standard type and not the dual mass unit hyundia said i required. could anyone throw some light onto my problem.......... please!!!!

cheers ............... mark
