This is what happened when a project car for Prestone turned “Defiant!”

It was a musclecar, yet not your traditional one. It was an anniversary, but not your everyday one.

“For our 90th anniversary, we wanted to do something special. We wanted to build a car. So we approached the two guys that have been defying the norm their whole careers.”

That is the basic backstory according to Prestone about why they approached custom-car builders Jim and Mike Ring of Ringbrothers, based in Spring Green, Wisconsin.

And the Rings had just the car for Prestone: a 1972 AMC Javelin AMX.
