Ok, show everyone the turbo poly that makes 600hp, gets mid 20s gas mileage, is relatively inexpensive to put together, and relatively inexpensive to replace when you blow it up.
You have to deal with the reality that keeping cars pure and original is death for a lot of them. Future generations want cars they can drive and enjoy. The more original and less drivable you make your car, the more likely it will make its way into the junkyard.
