The problem is that, wherever the line in the sand gets drawn, it is arbitrary.

In and of themselves, washer bottles don't make any sense. Neither does the requirement for stock wiring harnesses. Neither does the passenger window. Neither does the glass in the rear doors of 4-door cars. Neither does the side backseat glass of 2-doors. Neither does the rear glass. I can't find a windshield for my Cortina, so it only makes sense that I should be able to use Lexan like other real race cars. Fenders are NLA, too so...

This is a completely different isssue from classifying new cars, or aging old ones out. We need to be careful to separate the two.
