Buying a car isn't always a good experience. Annoying sales people, the financing guy, vending machines that don't work…it can all be a huge headache. Fortunately, J.D. Power has released its annual US Sales Satisfaction Study for 2015. It's essentially a comprehensive analysis of the new car buying experience from the customer perspective. The study measures not only a dealership's sales process but, more importantly, whether or not customers walked away satisfied.

Everything from the price negotiation, financing, warranty, and delivery process was taken into account. JD Power tallied the results on a 1,000-point scale. Brands that scored higher took advantage of technology, such as tablets, to demonstrate certain features or record customer needs. Below is the Top 10 list, in descending order. Audi: 728 Points/ Lincoln: 731/ BMW: 731/ Cadillac: 732/ Jaguar: 739/ Infiniti: 739/ Lexus: 741/ Mercedes-Benz: 749/ Porsche: 752/ Mini: 762
