Really well! It's getting back that was hard...
I've been meaning to post a long thread on what happened, but I'm waiting to finish removing the dust from the pictures first (there was a dust spec on my sensor which is now on every single picture I've taken!!!).
Proudest moment for the micra was dealing beautifully after I tried showing off... and drove into a lake. The engine (and snorkel) coped brilliantly, and not a drop of water entered the engine. Surprisingly, the ECU still works even though I was sitting in water up to my waist.... and thinking "f**k. I've really screwed up this time". We did have to get towed out (I turned the engine off when the water reached my waist INSIDE the car... was worried of hydrolocking it all), but after a half-and-hour in the sun, it was all good to go (not so much our passports, documents, and electronics, all of which were ruined).
Also very proud of her offroad... never got stuck, and she rescued a stranded Panda 4x4 in Turkmenistan.
Though you were right on the exhaust pipe... I hit a rock in the Pamirs between Tajikistan and Afghanistan, and we lost our exhaust pipe... duct taped it to the roof, and kept going as it nothing was wrong. In Uzbekistan, a helpful MSF volunteer brought us to a welder, who stopped having his dinner to reweld out exhaust on. He didn't want to get paid either!
