Cadillac bested Lexus and Acura for first place in customer experience by the New York-based Luxury Institute. Only those earning more than $150,000 per year can take the Luxury Institutes survey, which gages brand tastes of the wealthiest Americans. Among the reasons Cadillac came out on top was the overall dealership experience, looks, and performance. Audi, BMW, Infiniti, Jaguar, Lincoln, Mercedes, and Volvo were also eligible for the award. If you've never heard of the Luxury Institute, you're not alone. We didn't want to take their survey anyway.
