Interesting article in The Economist about the automotive retail channel, and why it is changing. Regardless, you'll likely be purchasing your next car from a dealer for the foreseeable future

"What motorists do want, though, is someone to talk them through all the features that cars come with these days—entertainment systems, navigation services, automated parking and so on. Carmakers are beginning to respond. Since 2013 BMW, taking Apple Stores as its model, has been installing “product geniuses” in some larger showrooms, to talk potential buyers through its cars’ features without pressing them to close a sale. Daimler Benz, another German premium carmaker, and even Kia, a mass-market South Korean firm, have begun similar initiatives."

I have no doubt that dealers will transition and work with manufacturers to deliver the services needed to make customers happy to keep driving sales.
