You might want to read this - from TÜV Germany, in English. The Prius has the lowest defects reported from TÜV in their inspections, in the category "2-3 years old cars". Toyota has the highest rankings in terms of quality and lack of defects. 3 models additional models, are in the Top 10. TÜV Report 2011 I hope that (my) Prius 2010 3rd gen will perform just as good!
