I didn't get a single call from the 30 day classified newpaper ad while selling my WRX. This really suprised me as the newspaper always resulted in the best responces on all previous cars I have sold via a private pary sale.

I would suggest trying placing a detailed ad on NASIOC.com, ClubWRX.net. If that doesn't work I go spend a little money on Autotrader.com and Ebay.

Here is a copy of my ad that I put together when selling my car to give you an idea:

I think it took about 60 days to sell my car.
