about the only thing that car has going for it is hope that someone cares about the low serial number. doesn't look very nice, especially for a FL car. but hey, maybe it runs like a top, too bad you can't tell that over e-gay.
I'm not sure what else would be in the curb weight that's not in the shipping weight, but that is a big piece of the 100 lbs difference ('88 Si curb weight is given as 2017 lbs). Maybe you got a light one.
