It could be a few things:

1) Oil dripping from the engine onto the hot exhaust.  It's probably an
    old seal or maybe a sensor leaking.  When the car is parked, open the
    hood and see if it smells worse in the engine bay. You might even see
    smoke from where it's hitting the exhaust.

2) Antifreeze. This wold be a sweeter smell. If it is stronger inside
    the car than in the engine bay, it might be the heater core leaking.
    Look for a wet, sticky spot in the front floor wells. The heater
    core is up inside the dash and is 8+ hours of labor to get to and
    replace.

3) If the car has been parked for a while, don't discount a dead mouse
    that made its home inside the ventilation system.  Stick you finger
    in the coolant overflow tank and smell it. Pull the oil dipstick and
    smell it.  If your bad smell isn't one of those, it might be a dead
    critter.

I CC'd the V8 list as they may have more insight.
