Well after test driving a 2003 and 2005 standard WRX, I decided to drive an STI for comparison.
The car I drove was a Silver 2004 WRX STI with 29,xxx miles on it. The car was awesome! It was a genuine supercar. I never expected the car to be that fast. There seemed to be an endless supply of power on tap...in any gear! I think I ruined myself a little bit by driving it, because now I have lost some intrest in the standard turbo WRX. All I can think about is the STI now.
The STI's starting asking price is $24,995. Is that fair? I could probably talk them down a little. But that seems like a fair price to start from at least.
Another dealership across town has the same exact car with 2,xxx less miles, same asking price, year, and color. I plan on looking at it tommorow if weather permits. I'll keep you posted.
