I just bought my first WRX, it's an 08 model. Not an STI I guess it's a base.
I don't know a whole lot about the different models.
I've been a fan for 10 years of them. I bought this one with less than 40k miles on it and bone stock. The one thing I would love to do is get a little more sound out of the exhaust. I don't want the annoying "fart can" like my son calls it. But i do love the sound of the WRX!
