I'm restoring my 1971 240z. Well, the engine runs really good but every time i drive the car, it smells so bad it makes me wanna throw up. It smells like exhaust and it gets all over my clothes and by the time I get to work in the morning, I smell like a dirty ol' mechanic. I want to restore my interior but the smell from the car is holding me back because I dont want the upholstry smelling like exhaust. Any ideas on how to get rid of the smell? I also notice that it smokes alot from the exhaust tail pipe. Thanks
