[93CivicSiD16HB]

Well assuming the paint isnt a stock color, i wouldnt try too hard to make it looks stock, leave the bumpers on and put a few big for sale signs in it, drive it around a little bit and even in a bigger city that you live near and show it off. If after some time (like a few weeks) no one has paid interest in it, go ahead and try putting the other bumpers back on as long as their going to be the same color, and repeat that again.

Now about your numbers.
I would say now with that new info, that you could maybe get 2500 for it MAYBE 3 if you find someone who really likes civics, try on here, honda-acura.net, and an auto trader type thing that sells just imports, (thats usually for faster cars though)
Honestly if it were an ex it might sell for 2-300 more or an si might for 1000 more. Just keep it super clean and drive it around alot with that FOR SALE for everyone to see.

P.S. If someone wants a 92-95 (its a late model too so thats good) civic and is really steering that direction, they'll just take this car and swap out the brakes tranny and engine anyway, so dont worry too much about it being auto, some actually prefer it!
