Hello, I have a 1999 Civic Si with 117,000 miles on it. It has been garage kept since new. It has an AEM cold air intake, AEM cams and gears. AEM short shifter, West Coast Wing, White MOMO rims, steel rims, Ceramic DC Sport Headers, new exhaust with high flow Cat. Only Mobile 1 synthetic oil has been used in it since new. The car runs great and doesn't need anything. Only a few minor cosmetic touch-ups could be done to the rear bumper and here and there, nothing serious. I bought it in 2007 from a 60 year old man, which is a good friend of the families, for $12,000. At the time he had someone willing to pay $14,000 at a car show, which he was in the process of getting back to the gentleman when I bought it.

So what would it be worth? I looked on eBay and car sites and 1999 Si's don't seem to exist..

 

They're tough to find these days. It would be worth more if it was stock.

 

Pics?

I would say $6k-$7k if the body is clean. It really depends if the person buying has been looking for that car for awhile and willing to pay that. etc Otherwise, to the normal person, they'll look at is as a more expensive Civic.
