99 Cirrus occasionally leaks oil

My 99 Cirrus occasionally leaks oil. I know this seems strange, but every now and again I notice that there is an oil spot on the driveway. My car is the only car that parks there. Does anyone know what would cause this?

Thanks for any help you may be able to give me.

More than likely a bad gasket(s). Get underneath and see if you can tell where it's coming from.
