okay this is nuts haha
First the new STi is defintaly unique...i would much rather have the 04-05 STi, but would MUCH MUCH rather have an STi in my body style or the older GC8.. just wanted to throw that out there.. the new STi in person is actaully a pretty cool looking car... but then again i love the bugeye wrx which most people think are ugly as all hell, its an acquired taste i suppose.
The 2.5rs is a great car regardless of the lack of a turbo. The car handles great out of the box, and is a very peppy motor... my buddy with an older gc8 body style mobbed his for the past 2 years, and just installed his WRX motor in it a few weeks ago.
Boost is a great thing. I love having boost, i thought about turboing a bimmer when i owned one, but just didnt want to deal with all the stuff that can happen when you turbo a car that doesnt come with one. and to avoid those problems would defintaly but a nice dent in my pocket haha. but regardless boost is great, when you are runhing 18psi on a vf-34 and pulling on an evo you get the biggest shit eating grin ever haha.
