You know you own an s13 when you know every other forum member who doesnt own one, secretly wants to...
...when you look enviously, jealously, admiringly at other s-bodys but know you wouldnt swap yours for the world.
...when after years of loving sil-80s you suddenly develop a unexplicable love for s13s that keep the pop-up lights (think koguchi power )
...when you're immune to the factory spec windscreen wiper squeak and only your passenger can hear it
...when you rinse much "newer" and more expensive cars and the driver of the other car has a look of surprise on his face when you go past
...when you take extra layers of clothing with you when your going for a drive (even in the summer), cost even if you dont need them to keep you warm they'll be good for moping up the oil/water/fluid spill or tearing up to use to block up leaking pipes.
...when only other s13 owners really appreciate this thread.
