Mr E John Cunningham

Modern cars are a puzzle palace.

And they’re getting puzzlier.

John E. Cunningham has spent more than 20 years wrenching on cars — diagnosing them, repairing them, and occasionally fighting with them.

A qualified automotive technician, he’s worked with Volkswagen Audi, Volvo, General Motors, and Land Rover.

He’s also the founder of RustyAutos.

His mission?

Make cars make sense.

No mechanic-speak.

No dangerously boring lectures.

Absolutely no fluff.

Just clear explanations, sharp visuals, and real-world know-how.

Engines. Transmissions. Electrics. Steering. Suspension. Brakes. Hybrids. EVs. And everything in between.

Car know-how for people who don’t know cars.

Cars can be complicated.

John’s books aren’t.
