Have been lurking for weeks and have read thousands of posts by now. Took the plunge and traded a Mercedes R500 for an white '09 GTS with 20k miles on it. It is a little light on options but the low miles were hard to pass up. The small issue ( I hope) is what appears to be condensate just in front of the rear muffler. It has no smell, a very slight oily consistency and leaves small, about 2" diameter spots on the driveway...have searched the archives like mad without success. Anyone with any ideas?

Check the space under your spare tire in the luggage compartment. It may be full of water and the drain hole plugged.

Thanks Andy; first place that I checked...bone dry.

Is it centered or to the left or right?

Possibly your exhaust clamps (located about 2 feet in front of the mufflers) are allowing water soaked with carbon residue to drip when everything's cold? Start up the truck when cold and lay under and watch to see if you can view the water dripping out. If not, the differential is the next bet...

right you are...condensate from the exhaust clamps. thanks for the help!
