True. stop-start might have not been the best example in this case. But still, i would be quite apprehensive of buying a 10-year old european car that has stop-start built in - Much more than an equivalent toyota. Japanese are quite slow to follow in implementing new features and as a result (IMO) their implementations seem to be more reliable. I have experienced European cars to develop serious electrical issues over the years. Couple that with a stop-start system, and you are looking at an undrivable car.

edit: In the past couple of years things seemed to have mixed up a bit in the industry (for example American cars have quite improved in quality). So who knows, maybe today's cars might hold up much better 10 years into their life , than their predecessors. But increasing incorporation of software and electronics into these probably will not help them get there.
