From the back and inside cover:

"Junk it!" - the insurance man said.

Hap first saw the red MG in Frenchy's garage. Enormous silvery wire wheels-rakish scarlet body. It had a personality all its own-arrogant, insolent, challenging. When Hap saw the other side he groaned; crushed, caved in.

"It cost you fifty dollars," said Frenchy. Hap's head swam dizzily.

Could he find a way to make the RED CAR sing and race again-for him?

"I've only got a hundred dollars," Hap Adams told the bandaged-wrapped racer.

Hap Adams is 16. The one thing he wants most in the world is the wrecked MG sports car.

To Frenchy, the garage owner, he had said, "That car is not junk! I'll work like a horse for you, doing anything you say, if I can buy that car and get it fixed up by fall."

How Hap gets a green light from his father, from Frenchy, and finally from the people of Bullet to buy and race The Red Car is a story for everyone who loves cars.
