I've always been a fan of these two. But always switching sides, depending on what age I was and what I knew of the cars.
When I was in high school and early college, I was an Evo boy. Mostly because of Gran Turismo 2, but it was the car for me. That was the car I wanted.
A few years on and I became an STi fan, and I've been on that side since then.
I just like that the STi is a very unique car. It uses a boxer-engine, not your typical engine layout. The engine sounds angry, even on idle. I've heard a few during stop light stops and wow. Talk about rumble.
Even though according to reviews the Evo is still the better handling car, I will still side by the STi. Even though the latest STi is a hatchback, I still side by it.
I don't know why, I just do.
But my ultimate dream STi is the 2004 model. It's the best looking STi ever, if you ask me. Just take a look at it:
Sweet car, right?
