I am driving spark for now 5 months with app 2400 kms already travelled on it. I felt tha t clutch gets little harder (on pressing down) after car has moved a few Kms particularly in traffic. I was also having some mild squeaking sound while pressing till floor. The service center has changed the clutch cable . It has improved but still I feel that last mile while pressing requires more effort. Has any body else faced any issue like this in spark clutch .The car also at times stall while taking of from stop condition. I was told that spark has manual clutch and not hydrolic . So it will not be very smooth.
Otherwise the vehicle is superb with very good ride.
