I personally prefer the 3 window cab.. to my eye it looks leaps and bounds better than the 5 window AMC Pacer looking 5 window cab.

My guess is the reason you see more 5 window cabs on the road today is because thats what folks like.. i've seen dead mint AD 3 window cabs go to the crusher, and when I ask why they'd do such a thing they reply, "if it hadda been a 5 window, i'd have kept it!"

an idea is only stupid if you think about it rationally.
