For $58,000 you could buy an 06 STI and make it faster and style it the way you want it. I'm guessing it will sell in the 40's.
The sti looks nice. Your right you could build a 06 for what you wanted but that thing looks ready to race. From the coil overs to the tiltin master cylinders. The cage looks pro and the whole thing has been gutted. If your looking for a track car ready to go thats a good price.
