i had same problem with my city 2007,driver 124000 km,i changed clutch plate,plus bearings.clutch is very soft now and the pick of the car has increased drastically !!
there are two versions of clutch plates,both are Japanese but one is slighlt better.6000 and other is 8000. labor was 2000.So my total cost was 10000+gear oil=12500(gear oil must be changed).plus many bottles of coolant for radiator as the whole radiator has to be opened.
it is a lenthly procedure.may take upto 5 Hrs depending upon mechanic.lot of engine opening.as the clutch plate is at bottom:P
m very happy that i changed it.
