The article is about being happy with your car, not being a happy person in general. And specifically it measures the answer to the question "would you buy this car again?". It's unfortunate that the word "happy" is used in the title. Wealthy people tend to demand much from their luxury purchases and have many options, so customer satisfaction is often lower for luxury brands, which is why Dodge outscored BMW, Volvo, Mercedes-Benz, and Lexus. If you look at the list, you see Hyundai outscoring Porsche as Hyundai exceeded expectations more than Porsche. But Tesla scored highest in terms of Tesla customers wanting to buy another Tesla as their next car. They do have good product people at Tesla and are doing a great job there. But I think part of it is that Tesla doesn't have many good rivals yet, so if you are wealthy and are determined to drive an electric car, you are much more likely to want to buy another Tesla whereas if you don't care about that then you have many more options. The list: Tesla Lincoln Ram Chrysler Subaru Hyundai Porsche Dodge Mazda Toyota Kia Mini BMW Ford Audi Honda Volvo Volkswagen Lexus Jeep GMC Chevrolet Mercedes-Benz Buick Cadillac Nissan Infiniti
