Yes, my wife has one as a lease car with the semi auto box and I've driven it a lot.
It's a good sized small car with a decent boot, reasonable handling and averages 62mpg (in the wife's hands and 57 mpg when I drive it!)
Reasonable turn of speed too.
I'm still not a fan of oil burners though!
For the £2.5k daughters car, can I throw the Daihatsu Sirion and Daihatsu YRV into the pot.
They are relatively rare, use the same engines as the Yaris (in fact the Yaris uses Daihatsu designed petrol engines) and are very reliable.
Daihatsus are built in Japan, Yaris' are built in France.
