I got a Seicento sporting and I get a horrid burning smell when I give it welly and when its pulling hard up a hill. It smells exactly like when brakes are stuck on but it cant be the brakes as the smell comes without even touching the brakes. The clutch doesnt slip but I have been told it may be on its way out. The cars only done 23000 miles and I wouldnt expect the clutch to go so soon. Thanks for any help.
