The Yaris for sure. I bought mine 4 years ago and it was 4 years old at the time. I've never had a spot of bother with it, costs very little to run, spacious and modern looking on the inside and they really hold their value. A great little car in my opinion, I have no intentions of getting rid of it for a while yet......
Drove both the Yaris and Micra and have to say I found the latter much more fun to drive.
