Q: Exhaust smell inside of the car - 1990 Mercedes-Benz 560SEL
The car that I have recently purchased has gone 125,000 miles. While I was test driving the vehicle, it ran great with no obvious issues. However, several days ago I was driving it on the highway when the odor in the cabin started to make me nauseous. It was a very strong exhaust odor. Is this caused by some leak? What might be the problem?
