My Sable tends to drip oil after we drive it,the drip seems like it is coming from the exhaust. The drip is very small ,in the morning there will be puddle about the size of a dime. The drip is coming from just beyond the oil pan in the ehaust.

Could be your transmission oil is leaking out. Would suggest you have it looked at ASAP before you ruin the transmission. Oil should not leak from any part of your car ever unless there is a problem.

I have to ask a question first: that small drip of dark fluid from the exhaust, does it eventually evaporate and leave a small sooty stain? When you say "oil pan in the exhaust", you probably are referring to the muffler, due to it's size.
What you are seeing sounds to me like simple condensation that is collecting come of the exhaust deposits before dripping out. Stop by most any auto repair shop and have this confirmed.
I hope this helps.
