Yes antifreeze is sweet smelling, burning oil stinks and gasoline is, well gassy.
It will fog up with moisture, the inside windows in the car, also accompanied with the sweet odor of coolant.
Any fuel spill,storage or leak can cause fuel odor inside the car.
Its probably the antifreeze in your cooling system. There is a good chance the heater core is leaking. Check the front passenger side floor to see if it is wet.
