Why would you have an exhaust smell in your car before you start the engine then once the car is driven the smell is nonexistent?
Any exhaust smell in a car cab indicates an exhaust leak somewhere along the line. Th reason you don't smell it while driving is because the air flowing air under the car is blowing the exhaust gasses away before it can rise into the cab. After the car sits for a while, the gasses seep out of the leak, and up into the cab.
