Problems with the ECU.
The car is very reliable and very comfortable, it can easily seat four large adults in comfort.
On the negative side the performance leaves a lot to be desired and the fuel consumption is a bit scary, especially during the colder months.
If you can live with the running costs though I would whole heartedly recommend one of these cars.
I get around 25-30mpg from my non turbo 2L SE, this seems reasonable to me. It all depend on what car or what basis you are comparing the MPG to.
