These are the highest quality cars: No breakdowns even after 100,000 km

German automotive magazine Auto Bild has a unique practice of long-term vehicle tests lasting up to 100,000 kilometers. Over the years, they have collected a rich database of dozens of models that have gone through extremely demanding driving conditions, and those with the fewest breakdowns have been singled out. Cars are tested in all weather conditions—from short city trips to highway driving—so the results do not represent just a technical analysis, but provide a comprehensive and reliable picture of their durability and quality.
