Oversimplification, much? Not like you're also getting dual mode suspension, all-leather interior, a better sound system, exclusive options, and a more-exclusive model.
A lot of people don't care about that stuff. They just want the extra seat motion.
What if you want all of the GTS features without the adjustable suspension? As in non-girly men who plan on doing aftermarket coilovers but would like the updraded interior...
Is it possible to get the SRT model with all of the GTS interior goodies? I'd sure hope so. It sounds to me like this 2 model system is a big mess that wasn't well planned. As mentioned in another thread, they should all be called "GTS" and everything should be an option.
The "girly men" comment was intended to be humorous.. so for all of you uptight people remember a lot of what you read on forums is tongue and cheek.
