Welcome Moncho, good question.
My immediate thought was "light blue touch paper and stand back".
On further thought though, I think that most on here, even ones who have had problems, will say that the reliability isn't such a big issue. Sure things are going to go wrong, but by and large it is a simple car and easy to fix, and any good mechanic should be able to work on it. You may need to wait for spares, so the thing could be off the road for days or even weeks, but generally they are a 2nd, 3rd or even 4th cars, so this isn't really an issue.
I'll be interested to hear others views on this.
