The study gives car shoppers insight into the new-car buying process and is based on responses from 27,831 buyers who purchased or leased their new vehicle in April or May 2015.
The study noted that car shoppers are increasingly tech-savvy and are drawn to dealerships that use the latest technology, including tablets and computer displays.
These devices "can substantially improve customer satisfaction," researchers said.
"Dealerships should understand that customers want and trust technology and that it can enhance efficiencies," said Chris Sutton, vice president of the automotive retail practice at J.D. Power, in a statement.
Edmunds says: Car shoppers may want to take a closer look at the results of this new study before heading out to showrooms.
