Crap fuel economy. (friend's two litre Mondeo does better!) Crap fuel gauge. Poor interior build and materials. Rattles caused by above. Crap interior light. Very little thought gone into design, eg; rear seat belt stowage, no space for oddments, laughable glove bag, luggage cover etc. .....as you can see, mostly interior related..... apart from that I'm happy enough. Wouldn't buy another though.....or another Toyota.....especially as the climate control is buggering me about already. My previous Yaris gave me no grief at all in over four years, now I'm considering moving next door to my dealer to save on fuel bills!
