I had a good look today as we got airborne from Bordeaux and there are actually two Mercures there.
Both are on visible on Google Earth to the north of the runway intersection. The first is shown facing south in a group of four aircraft (inc a Caravelle) and the second is a little further to the NNW and looks as though it might actually be outside the airport boundary.
The first one is in the Air Inter blue striped colours and the second is on the later white fuselage scheme. The first has either suffered from a starboard main gear collapse or it has been parked on soft ground as it is leaning to one side.
As an aside, the engineer who met or aircraft last night was wearing Air Inter waterproofs. They were obviously good quality to last this long.
