Aage Llievang tried explaining to his mother, but she shook her head. "Now, Aage. Really. Your own car? A car? What would the other co-op members think?"
"Mom, this is a classic! 1952 MG-TD. It's even--"
"British Racing green... yes, Aage. I know. Your father knows. Your grandmother knows. We all know about the car."
"But Mom, look." He waved his Handy at her. The MG glowed on its small screen. "There's one up for auction on carsforsale.com and I'm too young to bid. You've got to help me."
"Aage!" She put her hands on her hips and shook her head. "Your age is not the problem. You can't even afford it."
"I'd pay you back." How could he explain his fascination with the Vehicular Age to her? The seductive sheen, the rumble, the combustive power of automobiles called to him like a siren at sea. He coveted the sense of possibility inherent in the turn of a key.
And the MG-TD held a place high in his list of hope. British Racing Green, wood dashboard and a four-stroke engine. He had only seen one MG-TD, when he'd gone on holiday with his folks to the U.K. They had been walking down the street in downtown London. Most of the traffic had been pedestrian or cyclist. The occasional fuel-cell car glided by like a ghostly leftover from the Vehicular Age. Double-decker biodiesel buses roared past regularly, trailing the odor of fish and chips after them.
And then it came down the street toward them. A car that purred as its rounded lines soaked up the sun with a green so deep it was almost black. It pulled into the valet parking of a grand hotel and two people got out. Aage barely noticed them. He stared inside the car, where chrome and brass gleamed against a burled wood dashboard. The doors of the car shut with the heavy thunk of real metal. A valet pulled the car out of the parking circle and Aage never saw it again.
