New 1.33-litre engine at Yaris 2009

Hello, I have planned for a long time to buy my first Toyota – and a Yaris – soon. Actually I am interested in a 1-2 year old car, but the new 1.33-litre engine from model year 2009 seems to me also quite interesting… So I would be happy if someone could write some enlightening words about some of my numerous questions here. I have no idea, for example, how robust such a start-stop automatic is t. Can any of you assess this? Can you assume that such a thing would entail an increased maintenance requirement? Or is this already a sophisticated technology that works completely smoothly? Since it is a completely new engine: Do you think that one has to reckon with children’s diseases? And when should the new Yaris actually be available in Germany? Unfortunately, my previous research did not provide reliable insights. and price list? And a test report? Best regards, Stephan
