Better take a break from the books. Your logic is wrong. It's clear that if a wagon does not have a sunroof then it does not fall under your first quoted blanket statement; thus your first statement is invalid. It is Sunday so have a beer and watch football.
I just came back from the yards and found the wagon part I needed most- the license plate holder. Now I need the rubber bit bumpers that are found inside the fuel fill door. If they are there grab them for me! thanks ; )
