Have 153000 km on my Aygo which is about 95000 miles and the only issue I have is oil consumption, which is about 1L every 8000km so not a big deal. Just got my NCT(the Irish MOT) yesterday, it went through without any fails or advisories. Car has always been serviced by Toyota which I think helps. The handling on standard suspension is a bit cr*p so I fitted a set of Eibach lowering springs, which improved the roadholding with no loss in comfort. Would I buy another one? Well, I'd try the new Aygo and see, but probably would get a bigger car next time for comfort.
