hello everyone i just purchased a clk320 cabriolet and it has problems since i got it. the car is acting strange. it makes strange noises and does not work like it did in the first week. i don't know what happened to it. the car jerks sometimes and emits weird odors from the exhaust. i put my nose to it and took a good whiff of the exhaust while my friend pushed the gas pedal and its not good smelling. i have been taking care of this car like my own baby i don't know what is going on with it. i fill it up with the local "garo gas" 84 octaine here in pasadena on washington boulevard which my friend says is the best gas. it is much much cheaper than acro or chevron gas so I agree it is much better. i treat this car better than anything else in my life, what is wrong with it?? please someone can you tell me what is wrong?
