Just 20 months after Toyota Motor Corp.'s launch of the Scion brand, some customers are expressing frustration with Toyota and the car-buying process.

Scion buyers are reporting displeasure with the dealership experience, reported Forbes magazine. As young buyers often purchasing their first vehicle, many customers say they know more about the vehicles and their accessories than the salesmen do. And they complain that buying an xA hatchback, xB or tC coupe takes too long.

Toyota Motor Sales’ James Farley told Forbes that the problem is the time customers spend waiting for a finance manager to explain credit scores and new-car insurance. The financing process can take two hours, which is too long for the younger generation that demands instant service.

"These people are unlike any group the automotive industry has seen," says Farley, who is vice president in charge of selling the Scion brand. "They just expect things to work differently."

Toyota created Scion as a way to experiment with marketing and retailing concepts aimed at young buyers who will later be targeted for mainstream Toyota and Lexus vehicles.

Toyota dealers are now stocking accessories so they can customize cars onsite, reducing the time it takes buyers to get their vehicles. Some dealers are also trying out "straight selling," which allows salespeople to handle financing and service details often handed off to finance managers.
