rules for a rat rod? if it isnt inspired by the dodge prowler, if performance out-weighs comfort, and if it isnt covered in crap that is stricly decorational, its probably going to be considered a rat rod by someone. dont get me wrong, there are total piles of junk out there with intention to look rough. in my cars, i strive for performance, reliability and most of all how fun they are to drive. no fake stuff, nothing other than what it needs to go fast and be somewhat legal. shiney paint a nice chrome are what you worry about later when you get the money. so take a look at the craftsmenship and quality of work before you come up with a label to put on it.
