I've recently become the owner of a 94 C200 auto and there are a couple of things that seem a little strange. Firstly the accelerator peddle seems to have all the 'bite' in the last quarter (i.e. I have to push the peddle down three quarters of the way before I get any reaction). Also, although it probally just me using it wrong, the parking break doesn't seem to work. It pulls out and goes back in fine but it doesn't light up on the dash or hold the car. Do I have to push or twist something to activate it?
