Yeah, the Toyota Yaris is one of the two best in segment over here. I like the looks enough, it's not bad for a small/light car. But that's IMO
The other 'best in segment' is the Suzuki Swift. I'm pretty keen on it as well.
Otherwise, a new Clio? It looks ok, though it's probably starting to get a bit big. The Polo is probably getting a tad old for my liking, but not too bad I guess. Mini is probably too expensive? I'd stay away from the 206 and the Citroen equivalent, for reliability reasons. I don't want to tempt fate, especially since you want it as a vehicle for work.
