The automobile — connected to the internet, powered by electricity, driven with computer support — is evolving faster than at any point in its history.

Buying one, though, remains just about the same as always.

But luxury dealers are betting that technology, and a healthy dose of more personal interaction, can vastly reduce bad buying experiences.

“How do I have a sustainable business when everyone laughs thinking about car salespeople?” asked Peter Cooper, owner of Lexus of Lehigh Valley, in Allentown, Pa. “We’re so out of touch with the consumer.”

Aware that many buyers hate haggling, Lexus introduced a fixed-price program in May 2016, called Lexus Plus, in which the customer deals with only one person from beginning to end. Only 10 of its 238 dealers in the United States are involved so far; another three are preparing to enter.
