Which of the budget sedans holds up well in the long run?

Long term reliability is always a big factor for buyers of budget friendly sedans. While the Nissan Sunny has been around for a while, how does it shape up against its rivals in this all important area? I’m sure that there are some common issues that Sunny owners run into after a few years of ownership, so what are some of them? I will draw a parallel here between Sunny’s reliability and other widely sold budget sedans such as Honda City, Hyundai Verna or Toyota Yaris. What makes Sunny more or less reliable for the long haul? Factors that could apply include anything from availability and cost of spare parts to how often major repairs fall due, or whether the car can cope with high mileage without too many problems. The Sunny's long term reliability may be very helpful for giving potential buyers an informed decision.
