The STi is a great car, cheap to mod and a lot of fun. I think there are a lot of guys like me who had a GD STi and moved on to a 135/335 and in my case now moving on to an M3.
The STi will forever go down as one of my favorite cars ever. I learned so much in the six years I owned that car. It gave me a whole new level of passion and love for cars. But I'm realizing there's a big difference in what I wanted when I was 22 and what I want now that I'm (almost) 29. The M3 is just a dream come true to me.
