I also think the public's expectation of motor cars are a significant factor. In most of Europe, space is limited and roads are windy. So agile handling and good braking are usually more important factors than the amount of torque and kilowatts available. Also petrol is much more expensive here, so fuel efficiency is equally important.
But I agree with you that there are very few bad or unreliable cars - as they get more complex, there is a greater opportunity for something to go wrong.
In closing I have enjoyed discussing this with you, largely because you give reasoned argument and don't deal in sweeping generalisations. We come from significantly different cultures, but I think we have done well enough considering those difficulties.
All the best for the coming holiday season.
