1) As mentioned, the GT is a "tuned" by STi, so in effect if you buy all the STi parts and fit it to a std GT it then becomes a Tuned by STI car
2) The 07 t/b STI GT is probably more worth the money than the 05/06.
3) When i purchased my 05 GT, if i knew the t/b STI was going to be available, I would have probably spent the extra 5 grand or so and got it... but with my 07 GT i just could not justify the extra 17 grand for the t/b STI GT...plus i already have most of the same version of parts the t/b sti has and mine are better
But, the 07 t/b STI is a nice package for someone who can justify it and also its a great purchase for someone looking to have a slightly different car but are not willing to tune it to their liking.
