I read in Issue #15 of The Rodder's Journal in a feature on his 40 Ford (the same issue as Jimmy Shine's 34 Ford Pickup) that he built models as a kid and that influenced the kind of hot rods and customs he likes, and that he would stuff the biggest engine he could into a car.
So now instead of model cars, he has full size cars built. If I had the kind of money he does, so would I.
