My wife's Panda 1.2 and 2008 has done 180kkm which equals 112k miles. We bought it from new. Besides regular oil changes and spark plugs I have had to replace lower ball joints (or actually the full arms ... wishbones in English?) due to MOT failures. I have replaced the gear/transmission linkages, and I am going to replace the radiator also. The front brakes have been renewed twice. The rear ones are as new. I have replaced the rear muffler also and the timing belt 2 or 3 times (very easy compared to my Peugeot 406 V6 hehe). I have also replaced some bulbs and front drive shafts. I think that is about it. Still same clutch, gearbox and engine.
I think compared to Peugeot and Citroen, parts are quite expensive. E.g. the dual gear linkage cable was like 250 Euros.
EDIT: I forgot to mention that I have replaced the battery once.
